This is a good sale! Also, I saw someone elsewhere indicate that there is a $15 Target Circle reward for 3, $50 purchases, but sadly for me, I only see a $10 reward for 2, $50 purchases. But still, $10 or $15 is a good additional discount on top of the 15%! And you get an additional 5% off if paying with a Target Red Card!
The actual percent discount for this sale, BEFORE any Circle Reward, when paying with a Target Red Card, is 19.25%, so really great!
$50-15% = $42.50 - 5% = $40.375 / $50 = 0.8075
1 - 0.8075 = 0.1925 x 100 = 19.25%
