One thing that pissed me off is when you need to order a single small tiny item for $3 but then the shop charges you $14 for shipping.
GPScity charges realistic and actual shipping costs.
You want a single $7 ram part, shipping is $2, and it tells you right next to the items price how much shipping for that item is, you don't have to add to cart and start the checkout process only to find that the shipping costs 5 times what the item does.
Been buying my ram stuff from them for ages.
And their videos are great, sometimes you can't quit tell with just pics alone.
