Fukubukuro (福袋, "lucky bag") is a popular Japanese New Years custom, where shops make grab filled with unknown random contents and sell them for a substantial discount.
This is also popular at Anime conventions. At Shazmi's we are well known for having awesome grab bags! We focus on customer satisfaction not just getting rid of junk that won't sell. We have also split most of our bags into categories so the right series get batched up with the right fan. Nobody wants a bag full of things they have never heard of!
