I suspect that there are a significant number of people (including myself) in this same boat, who would gladly spend quite a large amount of TP during this type of sale, if only we could have the discount apply across all the purchases that the store requires us to do as separate transactions.
Perhaps some sort of a rebate system could be devised for this sort of sale. At the end of the sale period, the system looks back for each account, adds the total purchases made during the sale period, and credits the appropriate percentage of TP back to the account.
I, for one, would gladly have spent well over 3k points during this sale if it weren't limited to a single cart.
