Some companies I've had very good experiences with. :-)
Cheap Chips in Canberra, Australia sell every kind of flash memory for digital cameras and phones etc as well as card readers, USB flash drives, digital photo frames and lots more. Their prices and mail order service are outstanding and they'll look after you if you have any problems. Check them out!
ClamperPod, Mini Ball Head and miniOscarPod are great (digital) camera accessories I recommend. Don't believe the negative hype at http://gizmodo.com/gadgets/gadgets/clamperpod-when-crappy-gadgets-gocrappier-217157.php - these are all well-made products. I've had great success taking long exposures with my cameras clamped to my car window when using a normal tripod would have been inconvenient or even risky. Some people have no imagination or good ideas of their own, so they get their kicks by rubbishing those who have.
I bought a Garmin GPS receiver from them. Their service was superb, the price was low and the freight was free. Highly recommended. :-) (Some low-lifes broke into my car and stole that GPS. NEVER leave a GPS in an unattended car.)
My Laserjet 1020 printer made an abnormal noise from the day I bought it. When the warranty expired, I found it was due to a defective gear. HP Australia happily swapped the printer for a refurbished one even though it was outside the warranty and I'd disassembled it. How many companies would do that for a customer?
I had almost-incapacitating back pain for a couple of months. Three weeks after I bought a "Healthopedic" mattress from these nice people, I was pain free and sleeping better than ever. :-)
