Where do you find the postage stamps that are in good condition? Are they in sheets or individual stamps pieced together?
I just go on ebay,it's amazing how many are on there to choose from.I like new looking ones,as to me the postmarks look more like smudgy dirt.
Here's some tips that I have learned that might help others.....
I like to use the search feature to whittle down all the choices.I put MNH ( Mint never hinged) in there,then click on "USA only",then a keyword,then on the show catagory- rectangled box,I choosei, "lowest cost/shipping" Then I go from there,tweaking the search feature as needed.
You can also add,"Block plate',in the search line since then you get 4 stamps in a block plate together.
Sometimes there are some real values there.Othertimes,I'm in a hurry and use he buy it now button.I always search the "see other items from the same seller",to try to combine shipping.
If you are already a seasoned Ebayer,these tips are worthless.But if not,they have worked for me good.I'm always so impressed in the ease of shopping,and payment system they have.I've only had one not good experience,and the seller took care of it.
Take care,
Steve
