ok guys here is the thing
i make vinyl signs for semi trucks so am looking for a shopping cart that can do the following:

let the customer chose color of the signs, size, to input text of what they need like company name, city,state, and some numbers.
Also i will offer only paypal as a payment and would like to have a cart that is gonna be like one click buying and dont require people to log in and fill lots of information about them.
It is gonna pretty simple product just different colors and sizes.

So recommend me any good shopping cart either free or paid.
Thanks

hey mate, i have seen some good reviews of Bigcommerce online. Maybe give it a try.

Have a look at Magento. There are many custom options, it is free and you can find a lot of modules for this cart.

Here is the detailed listing of shopping carts with customers reviews:

There are a lot of good shopping carts.

I would recommend zen-cart for this purpose. You could use its free add-ons to achieve your goals. Of course, it is free, security, flexible and powerful itself. I have used it in building all my own e-commerce sites. :)

Have a nice day,
