I bought a computer there, along with extended warranty. When the computer broke, they didn’t know my name. That warranty was a third party vendor, I had to deal directly with them, yada yada yada.
A few years later, I went again - looking for a wireless router. They had two models, and I asked an employee what the difference was. Answer: “That one is 50 dollars, and the other one is 80 dollars”. Gee thanks.
That's another reason I like buying computers from Dell and other reputable online computer vendors. They do their own tech support of the systems they sell. They can provide one point of contact when there are problems with interactions of devices from multiple vendors. I prefer online tech support, because there is a record of the support session afterwards that is available in the future. I can save online chat sessions to a file on my computer for future reference or save emails.
