    No fuss, having a power supply that isn't supported on large online retailers and the ability to get a custom PSU power cord for my motherboard—I appreciate it. Also free shipping even though it takes a few weeks is also nice. Most places wait for the gotcha at the end with expensive shipping.

    The shopping experience survey shouldn't be done immediately after buying as I haven't received my order yet. However, so far my shopping experience has been great - no hiccups.
