Sale Price = $2.49 less $1 DQ (limit 5) less $1 Checkout51 (limit 3) = 49¢ (limit 3)
You could get a 4th and 5th if you wanted for $1.49
Today is the last day of the current Checkout51 week.
So if you purchase and redeem tonight, the offer may reset in C51 overnight, allowing you to get another set of 3 again tomorrow.
Well this offer reset, but it is now for $1 WYB2, so that will make them 99¢ each if you buy in pairs.
LIMIT=3, so you could earn as much as $3 if you buy 6.
Not as great of a deal. I am not sure if it spawned as needing to by 2, or if they changed it. I don't screen grab all my deals so I don't know. I probably just read the deal incorrectly before I shopped Thursday.
