I just bought one in the toy dept. of Wal Mart for $5.00. It's in the section where they have cardboard boxes of toys by price. For example, they have bubbles for $1.00, glittery balls for $4.00, etc. I bought one that is bright green with dark purple pieces in the spinner ball so I'm just going to call it a Buzz Lightyear spinner for my 2 year old son when we go to WDW in a couple of months.
I also bought two Tink spinners 50% off at Target the day after Halloween but that' won't be really helpful now. The Wal Mart spinner is actually a little bigger and the only thing that made the Target spinner a Tink spinner is a sticker on the handle.
