BuildASign offers a 3x6-Foot Custom Vinyl Banner for $38.21. Coupon code "19SLICKBANNER" cuts it to $19. With free shipping, that's $19 off and tied with our November mention as the lowest total price we could find for one of these banners, although we saw it for $4 less last spring.

Of note, the above code also takes 30% off all other banners. Plus, all orders qualify for free shipping. That's also tied with our November mention as the best general discount we've seen for these banners.
