Hi chelseaandco,

I don't think you need to narrow your choices to those 2 shopping carts. Last time I looked yahoo took a bite of every sale. Monster, I think, is part of network solutions now. shudder.

What you should pick depends on your expertise and budget.

OsCommerce right out of the box is a good choice. If you were willing to go with yahoo or monster commerce I think oscommerce is a better choice.

I've also done a few virtuemart stores. That's a component to Joomla CMS. I'm on the fence whether I like that or oscommerce better.

If you're going to customize the project maybe you could share more about the store's goals?
