..We haven't had a 'choose your discount' recently, but that would work nicely for this one. Just add one item and you're at 3000TP, which (in the past) unlocked the highest discount - 20 or 30%, I believe.
Plus, you're buying this with TP, not dollars, and the 'double bonus points' sale is pretty frequent too...
All in all, if you time it right, I think one could get this for significantly less than $30.
Honestly, this should be standard practice for anyone who is worried about their budget. Between double-bonus points, pick your own discounts, and sale items, you can save at minimum 25% on most everything, if you just plan ahead and know what you need to buy. IMO, of course.
