Ability to subscribe and renew periodically monthly or annually with email reminders, or auto subscribe with initial approval for auto subscribe.

so it could be possible to ask for specifics questions i.e. "is it a present ? Y/N" or "time of delivery morning or afternoon" or anything we can need depending of the specific business we do

Once someone orders a certain amount of products they can receive a percentage discount or a set amount or free shipping etc.

I did user-defined shipping calculations by weight - under a pound is one price, 1-2 pounds another, 2-5 (I think) another, up to the point where over 9 pounds is $12 and it doesn't ever get any worse than that. Now I would like to be able to offer free shipping over, say, $100 without messing up the other shipping ranges. If you agree that this would be helpful, please vote.

- will display a product price crossed out and new special price: For example the cart would display. Original Price $500 Now $450

the $500 could be in red and crossed out.

Bitcoin is a fiat cryptocurrency that is quickly gaining wider acceptance. I would like to see it enabled as an automated payment option.

As a developer i would love the ability to add additional users with ability to turn on and off functionality.
So i can create a new user for my client and not them tamper with css, and hide the widget codes fro them as an example.

Just as in Litecommerce you can have different "memberships" so also you can set up different types of customers here. We are a publisher, so we sell to regular readers as customers, and bookstores, and distributors. Each gets a different discount...

ie. add a checkbox for "this item is on sale", sale price field, sale beginning/ending or a discount on entire cart, maybe sales by categories/subcategory.

Add on cart/checkout part, "Customers who bought this product also bought this product ..." like what you have on the Amazon store. No online store for CMS sites, such as Joomla or Wordpress have this facility so you could be the first to apply it.

Easy manipulation of the head and footer, including a graphic.

Add support for HTML e-mail notifications (instead of just text/plain as it's now)

It woudl be great if this feature existed so we could interest a customer in another sale based on items they are browsing.

Allow the default currency to be changed to a local currency for cost reference by the customer, at checkout the customer will still be charged in the default currency but will see a reference cost in their local currency.

It would be good to make it possible to edit the invalid orders from the control panel. Customers often fill the order form with errors that may affect the value of the order and time of its execution. And no big corrections administrator, would reduce this impact to a minimum.
You can of course delete the order and ask to legalize it again, but I do not think this is a sure way out of the situation. Thanks in advance for your support.

Add "gift certificate" payment method.

It would be nice for Ecwid to be able to print shipping labels

For those who have a Paypal pro account why not offer the option in addition to Paypal express

The current Coupon system is nice, but it works for EVERY PRODUCT... Yikes! I need to be able to give a discount for a Specific Product, or a list of them... a list of SKUs would make sense.
