last year i mis-bought a ssd on amazon (wrong size or model i can't recall) so I asked for a return, surprisingly amazon wanted to save on transport that they offered to pay me to keep it (i don't want to spread stupid claim but maybe the full item price), i was confused and worried it would create issues down the road so i sent it back thinking i'd buy the proper item the month after.. and now i'm running duplicate search programs to save space on drives.
