Comparing BigCommerce to GoDaddy Quick Shopping Cart

I should start by saying that I have not been impressed by the usability of GoDaddy in the past.  I find their site to be overwhelmingly crowded with content making it almost impossible to find what you’re looking for.  

Prices
GoDaddy → $10/ month with no transaction fee (Economy plan)

BigCommerce → $25/ month with no transaction fee (Bronze plan)

Features
GoDaddy → Gives you 10 products at the $10 price
BigCommerce → Gives you 100 products at the $25 price, GoDaddy would cost you $30/ month for the same 100 product package (w/ Deluxe plan).  

Conclusion
For the site that I am building, where my client will be selling only two different products, I will be going with GoDaddy to handle my eCommerce needs.  Another factor influencing my decision is that my client already handles their sites online purchasing with GoDaddy, this means that they are already familiar with the product and will thusly require no/ little training.
