Might as well post my experience with one of those sites...
Before I found all the forums, I read about replica-center and all of that...then I stumbled onto a website which had the watch I wanted for so long, a 50th anni. Rolex Submariner, "much cheaper" then all of the sites replica center recommended...I paid $170 for it, From here. Now, the million dollar question...What did I get?
Well, what I got in the mail was a CD-Rom drive...yes, you heard right, a cd-rom drive, even came with the cable to connect it! at that point I thought I was scammed...but something caught my attention...it had one of those "void if removed" stickers which is broken...which led me to open up the cd-rom drive...Surprise, surprise what was inside? A Rolex! Brilliant...how the hell did a watch inside of a cd-rom pass thru customs I have no idea...the watch I recieved was almost the same as the watch I had ordered from Andrew, except it had a skinny minute hand, bad divers extension clasp, slow date transition, etc...
We are BLESSED to have the dealers we have here.
