So an interesting thing happened yesterday to another non-bitcoin related pre-order I made recently.
Dear Valued Guest,
Thank you for shopping at Toys"R"Us and Babies"R"Us!
We wanted to inform you that we have not yet received inventory on your Wii U Infinity Starter Pack pre-order which was expected in-store on August 18th, 2013. We will send you a follow-up email once this item is available and ready for pickup.
If I've learned anything from this thread then I should be getting out my torch and pitch fork, calling my lawyer, filing a complaint with the FTC, and starting a riot.
hahahaha.
I post this just to illustrate that even non-startups have problems fulfilling pre-orders sometimes

.
Have you demanded photographic evidence that they have in fact ordered the item? Have you sent someone to visit their warehouse to see if they're legit?
