UPDATE — September 9, 2026: LabSourced has extended its current sale for one more day. The promotion now runs through September 10 at midnight.

According to an update shared with LabSourced affiliates this morning, sales over the last two days have been exceptionally strong, so the company decided to keep the promotion running for another day. LabSourced also says it has recently lowered baseline prices on a number of products as its internal costs have come down and has added several new products to the site.

LabSourced sale details

• 30% off sitewide during the current promotion
• Use coupon code PEPDEALS for an extra 20% off
• An additional 5% Zelle discount may apply when using that payment method
• Extended deadline: September 10 at midnight

Because the discounts are applied to already-reduced pricing, the final price on some products can be substantially below LabSourced’s previous regular pricing. Exact savings can vary by product and checkout eligibility, so verify the final total before placing an order.

Why this extension is worth a second look

This isn’t simply an extra day on the calendar. LabSourced says it has also been lowering its regular baseline prices, in some cases significantly, as it has reduced internal costs and secured better pricing. That means the current percentage-off promotion is being applied on top of newer, lower starting prices on affected products.

The company also reported adding a number of new products while the promotion is active. If you checked the catalog earlier in the sale, it may be worth checking again before the extension ends.

How to use the PEPDEALS code at LabSourced

Visit LabSourced through the PepDiscounts link, add eligible products to your cart, and enter PEPDEALS at checkout for the additional 20% discount. If you’re using an eligible Zelle payment option, check the checkout total for the additional payment-method savings as well.
