Treats, not tricks
The tricks other sales play.
The treats in this one.
Seasonal sales are where research catalogs cut the most corners. This one is built the same way as the rest of the site: everything stated, nothing implied.
Tricks to watch for
- “Was” prices that were never actually charged, so the discount looks bigger than it is.
- Countdown timers that quietly reset every time you reload the page.
- “Up to” discounts that apply to one listing while the rest stay full price.
- Shipping that jumps once the code is applied.
- Sale banners that hide the documents, identities and policies behind the offer.
Treats in this sale
- 20% off the materials subtotal of any order — every listing, every format.
- Regular prices are the same per-format USD prices shown all year. The discount is taken off those.
- One fixed end time: 11:59 PM Mountain Time, October 31. The timer counts to that moment and the code stops working automatically.
- Shipping stays at the published flat rate. The discount line shows in your order summary before you pay.
- Every identity, document status and policy is exactly where it always is.

Sale questions
Before the
clock runs out.
Short answers about this catalog. Full policies are linked in the footer.
All customer questions01When exactly does the sale end?
At 11:59 PM Mountain Time, October 31, 2026. After that the code is refused in the cart, at checkout and by the server, and this page shows that the sale has ended.
02Can I combine it with the welcome or switching code?
No — one code per order. The Halloween code gives 20%, which is more than the 15% welcome offer, so it is the better choice until the sale ends. The switching code is also 20%; either works.
03Does it apply to every listing?
Yes. 20% comes off the materials subtotal of any order, whatever it contains. Shipping is charged at the published flat rate.
04Are the regular prices raised for the sale?
No. The regular price of each format is the same USD reference price shown on the catalog all year. The discount is calculated from that price and shown as its own line in the order summary.
