Please Define GV Configuration Options

Hello,

I haven't turned on gift certificates because the tax calculations were always incorrect in my test cart when a GV was applied. What I just discovered is that changing the GV values in the Order Total module seem to fix it.

My problem now? I simply don't understand what the options do, and I'd like to make sure they're set up correctly before I start selling GVs.

Can someone please define in layman's terms what these settings do to BOTH sale and redemption:

1) Queue Purchases
2) Include Shipping
3) Include Tax
4) Re-calculate Tax
5) Tax Class
6) Credit including Tax

Thanks!!!

It seems that "include shipping" and "include tax" describe if the GV can be applied to shipping and tax (of the order total). I set them both to true, and it appears to calculate the discount correctly..

But what do these (below) REALLY mean and how do they impact the creation and redemption of GVs and other coupons?

Tax Class
Use the following tax class when treating Gift Voucher as Credit Note.

Credit including Tax
Add tax to purchased Gift Voucher when crediting to Account
