User Groups & Buy Together

I have set up user groups. One group is set up with a promotion of 20% off. My problem is when they select a product with a “buy together” package, it takes the 20% off the already discounted item that is added on.

Item A is $1000…group gets it for $800

Item B is $20…group gets it for $16

buy together and Item B is $10 off for $10.

Put in a buy together and the user group gets it for $800 and $8. The user group should buy it for $816.

Is there a way to not let user groups see or even buy the “buy together” package?

Not unless you set it up as an Option Combination where it would have it’s own SKU.
