Possibly worth having a chat thread for some of the stuff posted on the bargains thread. Anyway, in relation to this:
Amazon Essentials Men's 2-Pack Slim-fit Crewneck T-Shirt, Pack of 2 - £4.04+ depending on size.

Even at that price not worth the money. Took a chance on them around Christmas and have never worn them other than to try them on. The fabric is quite heavy for a t-shirt, but the main issue is that the fit is terrible, particularly around the shoulders. They're cheap for a reason.
