How do I offer a sale on services that customers can purchase multiples of?

I offer skin care services, and am having an annual sale later this month. I'd like to send out an email to clients to purchase up to 3 of any service, for a discount. How do I only allow them to enter up to 3 in the Qty section? Is there a way to control the quantity of an item being sold online?

I do not know of a way to limit purchases with multiple variables. I would recommend, group 3 items together and sell them as a package. (Skin care 1 +Skin care 2 + skin care 3) = Super skin care package.

Since square will treat that as its own item, you have more control. Make as many as you need.

Bundeling your packages will work, you can apply a discount to the item and it will be applied at checkout.

If you have an enourmous inventory, this could be a challenge. If you have a limited selection, it should take you a few minutes to set it up, and have a very easy way to steer your guest to what you want to offer.

Let me know if this is applicable to your site.
