Obviously this deal only makes economic sense if you have somehow *acquired* a bazillion dollars in RRs and $5 cats that are expiring (for the OYNOs) or won’t be accepted at Jewel after the end of June (RRs).
Each pair of sun glasses rings up for $24.99. Use whatever combination of RRs and/or cats to get near to this amount. Pay the balance and high tax and get your $15 Jewel gift card. Run this deal as long as you want (well, assuming you don’t wipe them out of sun glasses), using the prior gift cards to pay the balance and tax. Are these really $24.99 sunglasses? Puhleez. But if you can sell them for five bucks, you’ve improved your rate of return. And since the $5 P&G cats didn’t cost anything to begin with, you’re actually coming out way ahead with a gift card that will not expire. I use mine to pay for tax, ’cause you sure aren’t gonna see me paying for groceries!
