added admin automatically bear button buyer buyers cart checkout code custom customers don ejejc example extra free function html item javascript lines option order orders page product products run scenario sell seller separate settings standard view wish

I'd like to run a promotion where if customers buy 3 products, one from each of 3 different categories, they would get a certain 4th product free. Is there a way to configure that so the cart shows they will get the 4th product? If not, we could just add it to their orders when shipped, but I'd like a way for the cart to show everything if possible.

Sorry, we don't have any way to add an item to the cart automatically based on any other item(s) being added to the cart. You could however add some custom HTML to the cart explaining you will add the bonus item to qualifying orders. Just add the following lines to your View Cart code on every relevant page, just before the "// -->" line in the standard View Cart code you obtained from Seller Admin:

function EJEJC_config() {
EJEJC_POSTCALL=true;
}
function EJEJC_shown() {
jQuery("#tdPmnt").attr("innerHTML",
"Order one item from <b>3 different categories</b>, and we'll add <b>Bonus Item</b> to your order for <b>FREE!</b>");
}

It seems there is not an easy to way to AUTOMATICALLY add the extra free item to the cart but is there a way to have a promotion that is if you buy PRODUCT A, you get PRODUCT B, for free?

For example, we want to promote our ebook so that if you buy an ebook, you get a free card mailed to you.

Is this possible?

Thanks.

Any given product consists of whatever you wish it to be, so you could simply sell the ebook with the understanding that product includes a card to be mailed to the buyer. Make sure you enable Shipping/Buyer's Address in the product's settings to trigger collection of a mailing address during checkout.

If you want to show the card as a separate item in the buyer's cart, you might consider creating a multiAdd to Cart button:

However, in this case bear in mind we have no way to prevent buyers removing the ebook item from their cart after they multiAdd the ebook and card, allowing them to place an order for the remaining bonus-card item without the ebook. Some sellers have devised custom javascript to handle this scenario -- e.g., if you go here, add an item to the cart, then add the backup CD option shown in the cart, removing the original item from your cart also removes the backup CD item:
