HDIS doesn’t do predictable holiday sales. Honestly, waiting on a sitewide promo is a waste of time. Your best bet is setting up their recurring Auto-Ship for 5% off, or buying full cases to dodge shipping fees. If you're a first-timer, sign up for their email list; they usually send a 10% code right away.

HDIS codes are super finicky. First off, they almost never stack if you’ve got their 5% AutoShip discount selected in cart. Also watch out for brand exclusions on bulk cases. If it’s a catalog mailer coupon that's refusing to apply, just call their phone line. The reps can manually push it through.

HDIS hides your exact delivery speeds until the last checkout step once you enter the zip code. Standard ground usually takes 3 to 5 days, but honestly, just turn on autoship if you want to dodge the $3.95 shipping charge. Everything arrives in unmarked, plain brown boxes anyway.

If you're ordering from HDIS, their referral program actually works, but don't expect instant credits. Your friend has to enter your info during checkout—sometimes online, but older relatives usually have to mention it over the phone. You get a credit toward your next case once theirs ships. Definitely stack that with autoship.
