What do you gain by 3x200 vs 2x 200. You can buy without a discount at staples everyday
My thought was it comes out to something like $1.50 for 600 = 3k points (assuming Ink for my purposes). That's 2k ppd.
Even though you're spending a little money (1.50), instead of making a few times that on the negative price of the sale (394 or so for 2x200 + fees - $20 = +$6 +2k points), you'll likely never get as good a value with that $6 as you can now on that $1.50. When this sale runs out, it's back to $7 or so for your 200 VGC. So while you're getting a (definitely good) deal with not spending any money for your points now, it seems to me you get more value overall by doing those later purchases now.
(Hence why I said someone who has access to lots of 200s, which is probably very few people on this forum lol)
