How does free shave gel sound? Grab a free can of Venus Shave Gel at Dollar Tree. Use either a printable or newspaper coupon. Get the printable coupon from coupons.com; just follow the link below. However, if you use the printable coupon, you’ll pay a quarter for the shave gel, but that’s still an amazing stock-up price! Or clip a coupon from the 11/26 Procter & Gamble newspaper insert for free shave gel.
