If you just made a huge purchase, don't be bummed out, you have 3 days to bring your receipt in and sign up.
Secondly, did you know that Target price matches!?! How did I not know this? Here is an example. I was debating on whether or not to get the Disney Princess Klip Klop toy for Georgiana for Christmas. I wasn't sure she would get $40 use out of it. I imagined Target would have a sale, but the $29.99 price still wasn't convincing me. Then, my aunt introduced me to price matching. Amazon.com had the klip klop for $24.99, I simply brought the toy and my phone to the customer service and they matched the Amazon price. My aunt had also forwarded me a Fisher Price coupon for $10 off the klip klop, bringing the toy down to $14.99. For getting up like a crazy person and spending over $75 at Target on Black Friday, I was given a 20% off my entire purchase coupon, so I added that onto the other savings, then there was the 5% from my red card, so in the end the $40 toy cost me $11.93. Between my two little ones, we will definitely get enough use out of it. Secretly, I love how the horses sound going down the ramps, impresses me every time, ha ha!
I hope this info can help you save money too :)
