They have l-carnitine at Target, if you have one near you. It will save you on shipping. Relacore, there's a really good price at www.vitaminshoppe.com... I think 34.95. But I got mine at GNC and got 20% cause the manager knew me from target. I dunno. Up to you I guess, but never buy pills or anything like that off ebay. It's too easy for people to fake the stuff.
