Having multiple checkout page templates/layouts would be a huge help. Your own trial registration page you use would work great for me because I also offer a trial and monthly billing, so please turn this checkout page into a template option for your merchants, for instance:
https://www.1shoppingcart.com/Signup/shopping-cart-signup1.asp

The decline for an invalid billing address, AVS mismatch, used to be displayed. Please provide purchasers this information once again. They should at least be told if this is their error (incorrect address provided) vs. their bank declining charges. It would be good to display the AVS return code on the online order, though perhaps not on the screen when the decline happens.

A customer had a problem -- they are using a package dropoff service for UPS (that holds the package for them), and the package dropoff service requires them to put a 5 digit code after their name. Currently, 1Shoppingcart doesn't allow numbers, etc to show in the Ship to name, so they got an error message. As these drop off services become more prevalent, it would be nice if the cart would accept a dash or other characters as part of the Ship To Name so customers can correctly put this information in and complete their order.

Please let us set the display order of products on the cart page. Right now they only show alphabetically - give us a way to order them, by price, or arbitrarily

Allow the minimum quantity for quantity discounts to start at a number other than 1. For example: I have a product that you must order at least 100 pieces, but you can order any quantity above 100.

Many people have failed transactions and abandon the cart when they do not change the TAB to select the correct card type. The feedback to them is that the card type does not match the number but they fail to see the tabs - even after this ... Can we change it to a LOGO which they click on?

I lose sales because people put a space in between each four digits for the credit card. I would like the ability to add a disclaimer next to the credit card field and/or the ability to convert the credit card info into four fields so that they can't put a space in between.

I'd like to see a return policy box that enables text to be entered that will print below the "Special Instructions box". It would also be great there were boxes formatted to allow the customer to enter the style number, quantity, price...of the item returned.

I currently have to change the state names on the shipping address to their 2 letter abbreviations for shipping labels. It would be nice if when customers choose their state it would just put the abbreviation on their shipping address instead of the full state name.

I don't need my customer's phone number, and it is off-putting to some people to be asked for a phone number. I would like to simply turn this input off from the cart setup page. Thanks!

Move, or create the ability to move, "Your order is safe and secure" from the top of the page to near the Submit Order button.

After a customer buys a product I need to generate license keys on our back-end app, then email the license keys to the purchaser (the keys cannot be done on the digital product in the manner I need). Currently there is no way to get the email address the purchaser used to purchase the product.

This can benefit small businesses that serve a specific, localized area. Correlatively, it can also benefit businesses that cater to the delivery of goods and services to a specific, localized area, but have customers worldwide. i.e., Filipino overseas workers who would like to purchase goods and services in the Philippines to send to friends and relatives who live in the same area.

We like to "recycle" buttons. It helps us so that we can use php code to populate the button information.

When I enter a customer's order, but I accidentally type in the wrong credit card number for example, all of the information on the screen completely clears. I have to re-type all of the customers information. Perhaps, have just the credit card field clear upon a decline, but all of the rest of the information still filled in.

I find that my fulfillment house won't ship to certain countries, but I'd still like to be able to allow digital downloads there.

On many e-commerce sites, the ""View Shopping Cart" icon is dynamic, that is, it shows a counter with the number of items currently in the cart (e.g., Amazon.com). I think that capability would be welcome on 1ShoppingCart sites

Since bit.ly links are now giving a 10 spam score, it would be great if we could create short links like bit.ly links in the product Quick Link Builder on the links tab.

The cart links are too long to put in a text email message, or to unmask in html.
