The Fine Print

Discounts don't stack. If one deal gives you a better deal than the other, we'll apply the best deal for you rather than both.

[1] Restrictions apply!
The discounted next item must:

  • retail for less than $100
  • be less than or equal to each other item in your qualifying offer

For example, Ticket to Ride costs $50, Pandemic Legacy Season 2 costs $80.
You can buy Pandemic Legacy S2 at full retail and get Ticket to Ride for $25 (half off). You can't pay full retail for Ticket to Ride and get Pandemic Legacy S2 half off.

[2] Excludes limited edition books. Of our current inventory, only Xanathar's Limited Edition Cover is not on sale.

[3] Qualifying Boxes:
Iconic Masters
Aether Revolt
Hour of Devastation
(If we had Modern Masters 2017, it would qualify, but we don't have any in stock!)

Free Gift-Wrapping

Lauren and co. will be headlining our team of holiday gift wrappers! She puts a great touch to any gift.

Fortunately, I (Luis) will be up front answering questions and ringing folks up. You don't want me wrapping your gifts! Occassionally my attempts at wrapping involve copious amounts of tape and not enough paper...

Lauren's wrapping will not disappoint!
