Are you an eBay seller? One item, ten items, or a full-time business you can donate a percentage of your winning bid to AMSAT. To do so, do not list your item with the basic listing tool, select advanced tools. eBay will give you a warning message that it is for large volume sellers, however this is where the eBay for Charity tool is found.
You can 'select another nonprofit you love' and search for either AMSAT or Radio Amateur Satellite Corporation. Choose the percentage amount of the sale you would like to donate to AMSAT and boom. When your item sells and the winning bidder pays, eBay will deduct the percentage from your take and forward it to AMSAT.
Sometimes we are getting rid of our old equipment, sometimes selling something new. In any case, won't you consider giving a piece of the pie to a new satellite and choose AMSAT for your eBay for Charity.
