Along with check and bookkeeping supplies, Extra Value Checks also offers face masks for if you’re looking to keep your employees safe, or just what to keep up a large stock for yourself or your family. You can even use an Extra Value Checks promo code to get a discount. Add on an extra box of ten disposable face masks to your order and you can save $6. Normally a box of ten masks is priced at $8.99, but when you bundle on an extra box of ten face masks, you can get it for $2.99. This is perfect for people who want to stock up on more masks.
