Recently, I decided to increase the memory on my computer. I did a lot of hunting and finally found a place called
MemorySuppliers.com. I had questions about the compatibility of a particular memory stick I was considering and they answered me by email within a few hours. Additionally, they had the best price for the Kingston brand that was recommended to me by my computer hardware guru.
Last but not least, they offered me $5 off my order if I posted a link to their site. I would not do it, of course, unless I'd had a good experience.
