D&D General good sales

[Quickleaf]

Anyone know how they do the math on that Amazon sale? Pay for the 2 most expensive and get the cheapest free or pay 2/3 the total value? Probably the former.

When I add TFtYP, Candlekeep, and 3-book Core Rulebooks Gift Set, then proceed to checkout...

Order Summary​

Items (3):	$150.92
Shipping & handling:	$0.00
Multibuy Discount:	-$28.96
Total before tax:	$121.96
Estimated tax to be collected:	$9.45
Order total:	$131.41

So they seem to be deducting the actual price (not discounted price) of the lowest value product, which in this case was TftYP $28.96.
