There’s a $33-off code doing the rounds at ModafinilXL right now ZW33QZ. Drop it in at checkout on any order of $500 or more and it pulls $33 straight off your total. Domestic shipping’s free regardless, so that’s the whole saving in one move. It’s time-limited, though, so it’s only worth anything while the promo’s still running.

What You’re Actually Getting
It’s a flat $33, not a percentage, which matters more than it sounds. That makes this a bulk-buy code rather than something to bother with on a small order.
- Code: ZW33QZ.
- Minimum spend: $500 before it kicks in.
- Discount: flat $33 off.
- Shipping: free on all domestic orders.
Because it’s a fixed amount, the bigger your basket the smaller the saving feels in percentage terms. So the sweet spot is hitting $500, not blowing way past it expecting the discount to scale. It won’t.
Using The Code

No mystery here, the code goes in the Promo Code box at checkout like on any other site. The only habit worth keeping:
- Apply ZW33QZ before you pay, not after.
- Glance at the total and confirm $33 actually came off.
- Don’t assume it worked. Codes like this expire quietly, sometimes ahead of their listed date.
If It Won’t Apply
If the discount doesn’t show, it’s almost always one of two things:
- Your subtotal dropped under $500 after you pulled an item out.
- Your delivery address falls outside the domestic free-shipping zone.
Both take a few seconds to check, and one of them is usually the fix.
One Thing Before You Order
Since this is modafinil and not socks, worth saying plainly: it’s prescription-only in the UK and a lot of other countries, and it doesn’t suit everyone. If you haven’t taken it before, have a proper word with a pharmacist or your GP about whether it’s right for you and how it sits with anything else you take, rather than committing to $500 of it purely because there’s a code attached.
