In terms of overall cost, customer service, ease of use in building and uploading/changing products, which e-commerce store builder do you feel is best/have the best experience with in terms of Big Commerce or Shopify or Store Coach (or another web store builder)?
I also know that Amazon has its own web store builder. How does that compare with the others?
P.S.: If let's say, I choose one (say, Big Commerce) and for some reason, I'm not happy with it and want to switch to another one, how much of a hassle would it be?
