Clothes/sheets/towels are all lower quality and higher priced in Argentina... For example, Jumbo has bath towels that are about the same size as the ones we just picked up at Marshalls, and roughly the same price (around US $8 each), but from experience, the ones from Jumbo are super thin and feel like they're worn out when you buy them, while the US ones are very thick and plush.
For the sheets... We have a King size bed in our apartment, and at Jumbo, a set of Polyester/Cotton blend sheets are about $60 while we got two sets of 600 thread count 100% cotton ones for $40 each at Marshalls.
Clothing, same deal. More expensive and lower quality, plus the Argie size charts don't really work for us... In Arg, I'm easily a 4-5XL while in the US, I'm an XL or 2XL, and my wife is a 2XL in Arg, while she's a M in the US.
