A price per format
Multi-format listings show a separate price for each quantity, so you never estimate or extrapolate.
Transparent pricing
A low headline price is easy to print. What it often leaves out is the identity, the right format, the documents and the policies you would pay for anyway — in time, in repeat orders or in a result you cannot use. Encore prices every format in USD, and tells you exactly what the price includes.

The true cost
None of these show up in the headline price. All of them show up later.
A lower price can describe a smaller quantity. If the size does not match your protocol, you buy twice. Encore lists every format with its own price so the comparison is like for like.
A product title is not an identity. Without a written name and CAS reference, or a stated component list, you cannot be sure what you are comparing — let alone what you are paying for.
A "tested" seal costs nothing to add. A report that names the sample, the date and the method is what you would otherwise pay a laboratory to obtain yourself.
A supplier that says nothing about pending checks leaves you to find out the hard way. Encore lists what is still unverified on the product page.
Refund and shipping terms discovered after a problem are the most expensive kind. Encore links Terms, Shipping and Refund & Returns from every page.
If something is wrong, a named business with an address and a support email is worth more than any discount. Encore's are in every footer.
Headline price vs full price
How Encore pricing works
Multi-format listings show a separate price for each quantity, so you never estimate or extrapolate.
The cart shows your total, and the server re-prices every order against the catalog before accepting it. Any difference stops the order.
Promo codes such as WELCOME15 (15% off a first order) apply to the materials subtotal and show in the order summary before you pay. Shipping is charged at the published rate.
Compare like for like
A fair comparison takes a minute per listing and avoids the most common way labs overpay: buying the wrong size twice.
View all productsCompare the same format, not just the same listing name. Divide by quantity only once both identities match.
Confirm the written name and CAS reference, or stated components, are the same on both listings.
Note whether a report packet covers the format you are pricing, and whether you can open it.
Read each supplier's shipping policy and refund terms alongside the item price.

All customer questionsThe server re-prices every order from the catalog before accepting it. If any price changed between loading the page and submitting, the order stops and asks you to review the new total. You are never charged a figure you did not see.
Claim the code on the page that advertises it, or type it into the Promo code box in the cart. The discount shows in the order summary before you pay. WELCOME15 gives 15% off materials on a first order and SWITCH20 gives 20%. One code per order; shipping is charged at the published rate.
No. Promo codes apply to the materials subtotal only. Shipping is always charged at the published rate so the total you see is the total you pay.
