Just bought a motherboard/package which claimed to have 3x 3GB DDR3 1600MHz RAM.
I did not immediately spot that 3GB sticks do not exist, doh, but equally it could be 3 channels of 3GB I am sure (2GB+1GB stick in each channel).
Yes, well, it turns out to be be 3x 2GB RAM, so 6GB not 9GB, making it not such a good deal.
Went back to shop, and took a nice picture of the display card http://k.gg/7978653 and then queried it. Obviously card removed very quickly and shop not prepared to fix.
OK, its a crap picture, but it was easy to take discretely, well, a lot more discrete than my 1D :-)
Sounds like letter to head office advising of a breach of contract. We'll see if we get 3x1GB RAM sticks...
Daft thing is I can honestly say I did not realise it was a mistake until we were driving away, so I was not trying to rip them off and exploit a mistake.
