Hit up the Bay folks. I got 3 or 4 belts from there while on sale as mentioned. I wear each once a week and they're holding up fine for 2 years now
Also, I got a casual belt (dark brown) from the gap many years ago and I wear it all the time when wearing jeans. Still going strong. As Roger mentioned, belts aren't really something I spend money on. Most of the time you don't even see it, unless you live in a tropical climate year round.
I don't wear suits to work either
