Since the days of caves, adorning walls with artistic shapes has been a way to document history, express feelings, and salute the handsomest woolly mammoth in town. Garnish drywall canvases with today's Groupon: for $10, you get $30 worth of decals, custom canvases, and more from Dali Decals online. Orders of $50 or more placed with this Groupon qualify for free shipping.

Dali Decals offers a wide selection of decals, murals, printed canvases, and modern mosaics that bring formerly inanimate walls to life. All decals are made to order using high-quality vinyl. Peruse the selection of decal standards, or submit your own image for a personalized, customizable addition to any indoor or outdoor wall or indoor or outdoor house pet. All decals, such as the cheery mushrooms ($19) or the set of six turtles ($10), come with a squeegee and installation instructions to make application as smooth and simple as possible. Anti-adhesive artisans are able to alter their accommodations with chalkboards ($29), which are suitable to hang in an office, kitchen, or any other shamelessly naked room. Products range in price from $10 to $300.
