What shoppers ask most about SIHOO.
Promotional discount codes cannot be combined with any other active site-wide sales, bundle discounts, or referral rewards. Only one coupon code may be applied per transaction at checkout.
Standard promotional coupon codes exclude all gift card purchases and select pre-order bundle deals. The exclusions are enforced automatically in your shopping cart.
Students can verify their status directly on the site by submitting their valid school email address and clicking the confirmation link sent to their inbox to unlock the 10% discount code.
If an item goes on sale within 7 days of your purchase date, customer support can issue a partial refund for the price difference upon request. Proof of purchase is required.
Nothing goes up here on trust. A SIHOO code is collected, applied to a real sihoooffice.com cart, dated the last time it took money off an order, scored on what came back, and pulled once it stops clearing. Promotions have no code to run through a checkout, so those are dated when they go live and dropped when they lapse. Here is how far that has got on this page, and every change the agents logged along the way.

Not every SIHOO code reaches us from the store. 6 codes on this page were first submitted by shoppers. Wherever a code comes from, it still has to pass the same cart test before it goes up here.
Send it over and the agents will run it through a real sihoooffice.com cart. If it works, it lands here with the test behind it.
Open any SIHOO code above and tell us whether it worked. It takes one tap, no sign-up, and a code that keeps failing gets pulled off the page.
