Bests & Worsts Reviews from Amazon

So I read quite a few of the reviews before buying these; I was weary about the cost being so little but the product/material being so practical and supposedly wrinkle free. I decided to order them, give them the benefit of the doubt; there were more good than bad reviews from what I gathered. BIG MISTAKE! As I was pulling them from the package I noticed that they're DEFINITELY NOT wrinkle free and were VERY DIRTY on the inside of the fitted sheet. It almost struck me as sneaky in that maybe someone wouldn't think to check the inside part and would have just totally missed it. I don't know if they were a previous returned item or if they came from the factory dirty (I purchased new ones according to Amazon, but I mean come on-these were gross) either way, no thank you. So I am returning them purely on principle, not even remotely about the cost. I actually got an E-mail from the manufacturer shortly after I got the sheets asking how I liked the product and telling me I can enroll my warranty. I promptly replied that they were dirty straight out of the package and I would be returning them. The company Bed Linens and More, did reply fairly quickly offering to replace them saying that if I hadn't already returned them there wasn't a need to, they'd quickly ship a new set. I definitely did appreciate the prompt response from the company, however it doesn't fix the off putting first impression. The other reviews I read here said they experienced the same thing and also had pictures of their sheet sets being dirty as well; I should have just kept scrolling.
