Online Shopping / Customs (Doha)

Dear all,

I have 2 questions on which I need your advice:

- What is the best local online store in Qatar for all kind of stuff i.e. electronic, clothing, accessories, home appliances? (Not asking for Groupon kind of thing)

- Did anybody have any problems with customs when ordered something from amazon or ebay? Is there a value limit in customs for certain products?

Inputs are very much appreciated.

Best
