Buy one, get % off on subsequent items

Hi,

The site I’m working on sells bamboo products (bedding/pillow cases/robes/etc) and has AwoCoupon Pro installed.

What I’m trying to do:
Make a coupon so that when a user buys more than one set of sheets, any subsequent sheets added to the cart will be 30% off (example: if you buy five sheet products, FOUR of them will be 30% off).

I’ve looked at the “Value Definition” part of the user_guide.html, along with a couple of the other forum posts in regard to this and have managed to ‘almost’ get there with a coupon I made, except for one small issue:

If these items are in my cart:

-sheetset1
-sheetset2
-sheetset3

After the coupon is applied, all three ‘sheetset’ products are reduced by 30% (when I actually just need two of them to be reduced by 30%).

So, in short, I’d like to know if Awocoupon is able to do this or if I need some accompanying component like the one mentioned here: https://awodev.com/forum/awocoupon/suggestion-box/buy-get-coupon-and-without (i.e. the “VirtueMart Purchasing Rules” extension).

Thanks!

P.S. I don't know if this is helpful, but here's the info that's in my current coupon :

COUPON DETAILS

-Function Type: Coupon
-Function Type 2: Product
-Coupon Code: Valentine
-Published: Published
-Percent or Amount: Percent
-Discount Type: Specific
-Value: (I left this empty)
-Value Definition: 2-30;
(note: in the popup for Value definition, I left “Apply Distinct Count” unchecked, so I don’t know if that effects anything)

OPTIONAL FIELDS

-I haven’t put anything in here yet

CUSTOMERS

-I haven’t chosen anyone specifically (as I want the coupon to be usable by anyone)

PRODUCTS

-I selected my various sheet products and clicked “Add”, so they’re now in the bottom right box

Hello,

If the sheets are all the same price then yes, you could do it, otherwise, no you cannot.

If using a 3rd party solution, verify the function can be done before purchasing.
