mexican wedding shirts (guayaberas) in so. cal.?

has anyone seen a place that sells mexican wedding shirts (guayaberas)? I would like to buy a few INEXPENSIVE ones prior to december 1. ive seen new ones on eBay, but i would like to refrain from busting out a credit card. i have a severe aversion to credit card usage.

THANK YOU!

I’ve spotted them twice in the JCPenney catalog. I nearly bought one.
