This deal is still available – but might end soon. Purchase the All You Magazine 1 year subscription for $19.99 plus you will get a $6.00 Shell Gift Card too! So that is like only paying $13.99 (or $1.17 per issue) after you factor in the gift card.
The All You Magazine can be found inside Walmart stores only, or through subscription. This is the one magazine that I actually like getting because there are TONS of coupons inside!
