Discount codes don't stack. If you have 56% off discount, they can't also use a "free shipping" coupon since Only one discount at a time can apply to a single order at the Diffuser World site.

Of course not, most coupons may be used only by you when you received them directly from Diffuser World. As the Diffuser World coupon includes your User ID, it cannot be resold or transferred in any way.

Normally, most of the websites you can print the grocery coupons from only work on a computer, even you can get coupon books mailed to your home for free. But it completely depends on Diffuser World's support program at the time you search, so please visit the Diffuser World site to know more details.
