US and International Buyers:  I can fit two or three shirts or other small items into a USPS Padded Flat Rate Envelope.  I will combine shipping and refund the lower shipping costs.  Two pairs of pants will also fit. So mix and match  When I run out of these that will be it.  These are the last that I will be able to buy.
