well i have been doing listia for years now, and allways did free shipping. but the post office just keeps going up. use to put something in a envelop if not to big for 38 cents. now anything thicker then a pice of paper is more. just to send a pick now is 45 and 20 cent stamp, + the cost of good envelops. and stamps are going up next week agen. so if i mail out 15 picks a week thats 11.25 a week or 45.00 dollors a month. and thats just for picks. hope this helps to understand.
like i sed it cost me 65 cents to send a pick in the mail, i pay for good envelops to send them. so i droped 10 cents on shipping for all my picks. you will see when it comes in the mail there is a 45 and a 20 cent stamp on them. if i just put a 45 cent on them it comes back saying to put another 20 cents on it. hope this helps. thanks
