Recently I bought about $2.5K worth of credit card readers from a credit card processor. During the integration process it turned out the processor was untrustworthy and a terrible partner (that's a whole other story) and so I looked into returning the equipment. I saw on their website they were going to charge a 25% restocking fee which really sucked (this is for a side-project) but it was worth it to drop them as my processor. After waiting 3+ days (and multiple calls/tickets) they finally replied to me "We've refunded you, please take the equipment to the nearest electronic recycling plant". I was very surprised (and a little happy I got back the full price).

Just to make it clear, these were battery-powered card readers (VP3300's [0]) that were still in their boxes with the original cords. I was shocked they wanted me to just throw them away. They are also very small and the box that held them all wasn't big or heavy.
