>>11319832I find the trick is to look for bundles of "retro electronic toys" or similar, those kind of bundles often don't list things by name so they won't show in the usual searches.
I got all of these in a bundle of of "faulty" electronic keyring toys (with a bunch of other neat stuff like Tetris Jr and some Puyo Puyo game) for only around £5, and most of it wasn't even faulty or had only minor issues like loose battery connectors
