Interview with John Barber
Metal Buildings are sold on a case-by-case basis. Questions call 1-888-512-1116.
Discounted Fiberglass Batt Insulation
Fiberglass insulation is often called fiberglass “batt.” It is still the most popular insulation type for pole barns and metal building structures because of its energy efficiency and ease of installation.
Did you know?
Most certified Insulations and I-Beam Metal Buildings sold in the USA originate from just a handful of large corporations. These corporations distribute the materials primarily through subsidiaries, retail outlets, regional representatives, contractors, and brokers. This means that even if you collected 20 quotes, you will still be reviewing the same material, just sold by a different reseller at whatever arbitrary profit amount they choose. They are not incentivized to offer discounted prices. Consequently, their lack of transparency often makes you cautious. Even if the manufacturers discount these outlets, these savings will unlikely be passed down to you.
By utilizing an independent broker, you are not limited to a biased perspective by a firm only selling one brand. Factory Steel Overstock uses its buying leverage to secure the lowest rates. The best part is that you see your savings first before paying the brokerage fee. It’s like having insulation and metal buildings for sale daily at FSO.
With Factory Steel Overstock’s unique discounted program, you can relax. You buy at the wholesale price, pay a brokerage fee, and eliminate the need for commission-based salespeople’s markups. Please don’t worry; FSO takes care of the order from submission to delivery and beyond, ensuring a seamless experience with our A+ Better Business Bureau and 5-star rated service. Testimonials.
Factory Steel Overstock’s spiritual approach was the brainchild of a 35-year industry veteran who believed customers and sellers could authentically work together, benefiting both parties equally. Because of this approach, FSO’s new orders come from repeat customers, referrals, and organic search engine inquiries.
“We can present YOU savings because we have the buying leverage, expertise, and specialized knowledge to do so! – Owner John Barber
Imagine you’re in the market for fiberglass insulation. The traditional way to proceed is to approach different outlets and ask for a quote. Then, you patiently wait for all your quote requests to return, hoping at least one price will excite you.
But consider this: What if randomly requesting quotes from traditional outlets is the problem? What if the quotes that come back are higher than expected? What if the materials quoted are slightly different on each returned quote, making it difficult to compare them accurately? In such a scenario, what should one do?”
Now, could you consider choosing a different starting process? Instead of depending on traditional outlets to give you their quoted price, you calculate the wholesale delivered price online, verify a savings, and then purchase for a low flat brokerage fee.
With Factory Steel Overstock, you buy from an independent broker that has maintained an A+ BBB grade and 5-star rating since its inception. Think of it like this: Factory Steel Overstock helps you buy something for less than you can buy it on your own. You pay the certified supplier directly and pay FSO for the savings provided. It is a risk-free savings program. You pay nothing until you see the savings!
Why Traditional Companies Don’t Share Their Actual Cost?
Have you ever wondered why traditional fiberglass insulation outlets hesitate to reveal their wholesale price or let you buy online? Essentially, these sellers worry that if they disclose their wholesale price, the average buyer will request or demand a price reduction. Therefore threatening their profit margins. Also, selling online reduces margins. It’s that simple! These sellers know the more ignorant the buyer is of the actual cost, the higher the probability of earning more from them. Moreover, offering retail prices ensures the seller a cushion for negotiations.
You’d like to know the wholesale fiberglass insulation price because…
- You want to be empowered!
- You don’t want to haggle!
- You want the assurance you are not overpaying!
Traditional companies don’t want you empowered. If they did, they would sell with full transparency!
About 15 years ago, a friend suggested I use a car broker for my vehicle purchase. I went ahead despite my initial skepticism due to a $500 upfront fee. To my surprise, the broker presented the car with all the features I requested. The best part is that it saved me thousands of dollars! This inspired me to present an even better program: Reveal an actual wholesale cost that confirmed savings before expecting ANY fee payment!
The misconception that “you get what you pay for,” touted by retail sellers, leads the majority to believe that higher prices equate to better quality. This misconception drives people to stick to the outdated practice of seeking quotes from traditional retail sources, thinking the best deals are only there.
Many need to realize that traditional outlets inherently charge retail, as there’s no incentive for them to do otherwise. The more you pay, the more they make! The public, conditioned to accept retail practices, continues to pay retail fiberglass insulation prices without considering the obvious. They will always pay retail unless they buy from a source that is not financially motivated by increased profits.
Since Factory Steel Overstock posted the brokerage fees upfront, offering the lowest wholesale prices is in their best interest.
You have two choices: keep requesting quotes from traditional retail outlets or utilize Factory Steel Overstock’s buying leverage, expertise, and specialized knowledge.
“Easy process. Do your homework, know what you want when you call and you will save $$. I saved hundreds over other prices I got.” – Brad Lezzi 1/10/2024 (Fiberglass Insulation Order)
