sales are only good at the linked venues (ie, if the linked shop is a
Zazzle shop it's not good at my CafePress or other shop I have).
Coupons and sales can not generally be combined...if there's a bulk
discount you will get whichever deal is better, not both. For stamps,
discounts apply only to the net value, or the value of the product minus
the USPS price of stamps. Not good on fabric, Brikk iphones, or Zazzle
Heart items unless sale is specifically noted for these items.
