Hi,
A plugin, but for what exactly ?
The "buy one get one free" can actually be done by default. Just have several prices for the different quantities in your product for example. Or a coupon with a 50% discount value on that product.
The "meet a certain dollar value and get a gift" can also be done quite easily with a small modification of the "cart" file of the "checkout" view where you would just compare the total value of the cart with the amount you want and then display a message if the cart total is higher. It's two lines of PHP really.
The "buy a specific product and get a specified product" is a bit tricky as it requires:
- to be able to select a product for another product, so some kind of custom field might do the trick
- to be able to have in the cart a product that you already have in your shop (or maybe not ?) and have its price be 0 but only if the specific product is also in the cart.
So that would definitely require a plugin.
The thing is that everyone want some kind of marketing like that but always a bit different. Someone will want a "buy a specific product and get a specified product", someone else will want a "buy a product from a specific specific categoryand get a specified product", someone else a "buy for at least a certain amount and get a specified product", etc.
As there are many many different cases, it's complex to try to have a generic plugin to handle all the different cases.
On the other hand, custom plugins to handle that can be done with a few lines of code so aren't really expensive to make. You can contact our partners if you need someone to work on that for you:
