I suppose the most I've spent would be around $35 (years ago!) and I usually spend around $10-20. I like very basic & plain jeans from Wal-Mart -- I think they're called 'Ranglers' or some such -- and I usually buy one or two pair when I'm visiting back in the States. I wear 'em 'til they wear out or fall off (I've been losing weight).
Do you like to go or have you ever been camping? If so, did you camp in a tent or have an RV?
