Thrifty Thursday - Goodwill Score

Check it Out!  I don't frequent thrift stores very often.  I did however go into Goodwill the other day searching for some cheap crafting goodies.  I didn't find any, but I did find this.  Just sitting on the shelf.  

Umm, yes it's a Yeti 30 ounce Rambler...brand new with the stickers inside and outside and not one scratch or dent.  Umm... do you see the price?  Yeah, I paid $4 for it!  I am left a little confused as to who would donate this to Goodwill, but hey, it's my thrifty find for the month!!  

Do you frequent thrift stores and have you ever scored an amazing deal at them?
