How to create a bundle of 3 with DSers on my online store?

[nmy2]

Hi Guys, hope you can help me with the following; I am just starting out:

I found a product that I have imported to my store, it has a size variant (S/M/L) on Aliexpress and also Quantity Bundle (2) for each of those Sizes. They are seperately imported to my store, so all the sizes variants 1 or 2x Bundle. They are already listed as a bundle of 2 on Aliexpress.

I also want to add a bundle of 3 on my store, how should I do that and fulfill with DSers? Should I remove the (2x) Quantity as imported from the supplier and just use a bundle app? (Because the supplier also creates discount for the bundle of 2)

hope someone can clearify for me, peace out
