I believe it was Forrest Gump who said, "HDX branded products are like a box of chocolates..."

I got that same pkg. of towels 3 or 4 months ago. There was a promo bin right as you walked in the door, The weird thing was, it didn't say anywhere on the pkg, the quantity inside. I asked the guy pulling door duty if he knew what the deal was with them and he didn't so he called over to cust. srvc. They didn't have a clue so they called the pro desk (Why, I have no clue...) By the time people stopped calling other people asking about the quantity inside the pkg. there were 6 employees standing by the bin including the M.O.D. who assessed the ridiculousness of the situation and ripped a bag open, handed it to the original guy at the door and told him to count them and to get a sign on the bin then told the rest of the makeshift crash team to get back to work. :laughing:
So, when I learned there were 30 in the pkg. for that price, I grabbed a couple of them. They're my go-to towel for anything non-paint related. They're tough, they clean up well and at that price, if they get something nasty on them, they're disposable.
As for hit and miss on the HDX stuff, I agree completely. Their Magic Eraser clones are far better than the name brand ones and cost a third the price. Their spray bottles are complete garbage.
