It is iffy, especially since most of them are pay first and the product ships after production. There are a few very reputable people who do it often, who are honest and have made a name for them doing this.

I have found the most difficult part is finding a US group order to save on shipping, or paying a huge shipping price to get the items you really want. Sometimes I cave and pay the large shipping because I really want the pin!

To keep track of what is available I started a google spreadsheet, but it really is more than a one person project. I know I don’t have a lot of them marked down.

It may be worth a thread if there is enough interest. Something for this subreddit to ponder.
