I placed two orders with sticker.com back in July, received proofs, order confirmations, and my credit card was charged. But as far as I can tell, nothing was ever shipped.
Over the last 14 days, I've sent emails to every email address I've been able to find at the company, and I've made several phone calls to a voice mailbox there but I haven't heard a peep in response, complete flatline. I even pulled up their domain registration information looking for contact info. As far as I can tell, the company no longer exists.
The order numbers are: 421970, 422029
If anyone is interested, feel free to contact sticker.com and ask about my order.
