You can use your existing digital products (or create new ones) to sell all photos within an album.
When creating or editing your price list, scroll down to the products section and select the "Per-album pricing" option in the select-box on the right - you are now in the album-products editing mode. Then simply click the "Add Products" button to add one of your digital products. You can conveniently create a new product right from the price list editing page by clicking the "Create new product" button. After you have set your price, assigned and saved your price list, your visitors are now ready to buy your whole album for your price.
The "Buy" menu now contains a new entry on the left side - your album product. You can see an album product as it appears in the cart, in the screenshot below. Your coupon codes can of course be used with album-products as well - by setting a minimum order price limit, you can effectively restrict specific coupon usage to album-products.
Depending on whether you have manual or automatic order approval selected, you may be notified of a pending order. You can then replace your photos by higher quality ones or with software-correction applied. After your order has been approved (this happens automatically if you keep the default settings), your customer will receive an e-mail containing a link to the individual photos from within an album and a link to a zip-file containing all of the album's photos.
