This year it only takes 10 jumbo wrappers or 50 regular hobby or retail wrappers to get a pack. This years theme for the redemption is the Silver Slate and there will be autos mixes in again as well. You can see a full write up over at Cardboard Connection.
Topps says you can bundle your wrappers together for multiple packs. Limit 10 per household and there are only 10,000 packs.
Here's the address to use when you get your packs ripped tomorrow.
Silver Slate Wrapper Redemption
PO Box 2008
Duryea, PA 18642
No word if there is an expiration date it'll probably run till the packs are gone and Topps has promised to put out updates on its Twitter page. The only stipulation is you can't send wrappers in till after Jan. 30th.
I'll be featuring my Jumbo break here probably Thursday after I get done ripping.
