Gamestop.com has everything from Hidden Fates in stock (except for ETB pre-orders atm) and at MSRP, the only problem is their shipping policies are beyond silly. Like two nights ago I went to pre-order an ETB while they were still available and got the "You must buy $0.01 more in product to qualify for free shipping"... which is annoying, but fine, I work for Best Buy, I know how that game works. I threw in a single Unified Minds pack get over $50 and then it wanted to charge me $20 to ship both the box and the pack because they were ruled as separate orders with no way to combine them. lol?
Their shipping policy is not whack - it's very fair, I believe.
Since you work at Best Buy, you might know that usually you
cannot combine a pre-order with something that's already in stock! This creates confusion on the merchant's side; they are thinking:
"Do we ship it to you
now? But we don't have the pre-order item yet. We have to separate the order and charge shipping for each delivery."
Also keep in mind, they will not hold onto the pack just for you and wait for the ETB's release.
If I were you, I would order on the day the ETB is released, and buy the UM pack and ETB together and get free shipping without this hassle!
