Ebay has a new targeted promotion with free $5 to spend on their website. You’ll get $5 off an order of $5.01 or more if you use promo code FUNFIVE at checkout. The code is valid until 3/4/19 and it’s YMMV. You just have to try it for yourself and hopefully it works.
They also sent out a $5 unique code by email today to some customers, so make sure you check to see if you were targeted. That code is valid until 3/19/19.
