I've bought from WWE Euroshop before, which was a Jeff Hardy pendant and 2 DX wristbands. But I usually by WWE merch else where, for example I just bought Wrestlemania 26 Deluxe version from HMV for £17.99.
That was a long time ago, I think it was around the beginning of the SES, or.....something.
I only buy shirts or hats (I have a Punk hat as well but that's my sole hat purchase) from WWE.com, I'll never buy a DVD or anything like that, I get those from HMV in the mall. I'm not bothering with delivery or shipping on a DVD.
I doubt I'll be buying anything from them in the recent future. When Miz finally gets a decent shirt or Alex Riley gets one, that will be my next purchase.
