The lowest price per mg we track comes from Half Nattys at $2.33/g. Prices change often, so check the vendor before you buy. See the table on this page for vendor rankings, including any active coupon stacks.
Do all vendors accept the same L-Carnitine coupon?
No. Coupon codes are vendor-specific: a code from Vendor A won't work at Vendor B. Each row in the table below shows which vendor's checkout the code applies to. Apply only the code matching the vendor you're buying from.
Are L-Carnitine coupons stackable with bulk discounts?
Stackability depends on the vendor's policy. Most vendors allow ONE promo code per order: a coupon OR a bulk-tier discount, not both. A few vendors (typically the larger storefronts) allow stacking; check the vendor's checkout page after applying the code to confirm.
