They are scams, as these dbags don't mind making up new accounts and scamming a few people out of small BTC with no recourse, thinking they are getting a deal.
BEWARE people.
Rules for picking out scams :
No Escrow = SCAM
Escrow, but pay for shipping upfront = SCAM
Also, the old Bait and Switch.
They claim to have on hand item for shipment, yet after dealing, turns out they are for 'pre-order' or future delivery date.
Only a moron would buy something with a future delivery date knowing the difficulty increases and possibility of a total SCAM.
I think this posts should be sticky on the page so everyone can see the latest trend that unscrupulous individual are bent on exploiting just to rip someone off his hard earned resources without any recourse to conscience, morality or even karma.
But unfortunately some people will still fall for it despite the several warnings on the forum and even something like this. I have come to realise that majority of the people selling around here are just newbies account, that alone is enough as a flag for anybody to not only be careful when dealing but be extra careful as new skills are being churned out every time to scam.
