Ok seriously, whats really the difference between that and drop shipping? The fundamental principle of retailing and sales is BUY LOW SELL HIGHER. How is this a scam? Every single business, corporate or individual, that sells goods MUST adhere to that basic principle to survive. Period.
Im assuming you didnt believe the seller manufactured the item themselves, so you must comprehend that somewhere down the chain to your hands a big business got paid for the item.
You saw an item you wanted at a price you were comfortable paying, so you purchased it. It sounds like you received what you ordered so wheres the issue? If it was an impulse purchase or you didnt shop around, thats completely on you or anyone making a purchase ANYWHERE. No scam here. Im sorry but I simply see NO LOGICAL BASE to this assertion.
(I am pissed I hadnt thought of it lol)
