Home Depot - Mavis Rd

I went into Home Depot to look for blinds. I found ones I liked and called the Home Depot to have someone come over and take a look at how much the blinds would then cost me. What ended up happening is that a Home Depot rep came over and before he began told us that if he did an estimate, it would cost us unless we purchased the blinds. Honestly I think an estimate should be a free service considering it is not complicated at all and requires just a few measurements. It also makes you feel pressured into buying the product to since you don't want to lose money. Thank god I liked the blinds, so I went ahead and got everything done, but I didn't like the idea of paying for an estimate at all.
