Is there a limit to the number of SKUs or shopping cart items on my eSite?
Shopping carts and Stock Keeping Units (SKUs) are only available with an Executive or Commerce eSite. Executive eSites can sustain a maximum of 500 SKUs; Commerce eSites are limited to 1000 SKUs. You may add as many SKUs as your disk space will hold , up to those limits. You may purchase additional disk space in blocks of 25MB for a $5/month charge.
