Had the same happen to me with Reddit Gifts for the Teachers. My first match was a dream to buy for and she sent me a wonderful thank you letter. You could just sense she really, really appreciated what I sent.

I had a bit more money to spend so I registered to have another match with the second-chance thing (don't remember how it's called). This guy had a very long list of expensive stuff for his comp class and some more basics supplies (stapler, whiteboard markers, graph paper, coloured pens for diagrams drawing). There was no way I could afford the computer stuffs (things like video cars, motherboards, hard drives, server racks, all with very specific parts #, etc.) but I thought hey at least I can send him the basic stuff. Holy shit the guy was pissed off. I got a nice worded message saying that when someone ask for a server rack and a stapler, they don't really expect to ONLY get the stapler. It's like dude, your asking for thousand worth of computer equipment and peripherals, don't be pissed off when the random person you got assigned to don't have thousands to spend on your computer classroom (if it was indeed for his classroom...)
