I shop both Amazon and NewEgg. Overall, there aren't any major differences. I rarely use the Marketplace vendors on Amazon and then only if they have a high customer review rating (I actually read the reviews rather than use the rating since many of the vendor reviews are actually product reviews). I never use the Marketplace vendors on NewEgg because there is no reliable way to determine how reliable they are.
Some comparisons include:
1. Amazon has free shipping on items shipping from their warehouses on orders $35 and over. NewEgg only has free shipping on selected items.
I have Amazon's Prime membership so I get free 2 day shipping.
2. NewEgg usually fills orders within one business day, often on the same day. Amazon takes longer to fill orders, especially when free shipping is involved. Delivery time is usually faster with NewEgg because they ship from one warehouse in CA. Amazon has warehouses all over the U.S. so the time it takes a package to arrive is highly variable.
Haven't had any problem with orders filled here. In fact over the years I'll say I've had basically a 99 percent on time fill rate here.
3. Amazon and NewEgg seem to use about the same care in packaging. I haven't had a problem due to poor packaging nor a problem with missing parts. I had one DVD from Amazon that wouldn't play completely; Amazon immediately replaced it. Both have similar return policies.
That's great to know.
4. In AZ, where I live, I have to pay sales taxes on purchases from Amazon because they have a warehouse here. NewEgg is out of CA so I don't have to pay any sales taxes. Your mileage will depend on the State you live in.
I live in VA where we are now paying taxes. Newegg isn't yet collecting taxes; so in addition to lower prices, taxes are also a factor
5. NewEgg offers extended warranties (for a price) on many products. Amazon does not.
Actually Amazon does, it's usually in a pop-up box.
Which one I order electronics from is determined by price, need or desire of an extended warranty, and availability.
Agree; though I usually opt for customer service as well, and for me, I'm very comfortable with Amazon. However, taxes, and higher prices are making me look at Newegg here.
