W. Va. Code § 46A-2-108: Cross-collateral.

In addition to contracting for a security interest pursuant to the provisions on security in sales or leases, a seller or issuer of a seller credit card in a consumer credit sale may secure the debt arising from the sale by contracting for a security interest in other property if as a result of a prior sale the seller or issuer of a seller credit card has an existing security interest in the other property and such debts are consolidated. The seller or issuer of a seller credit card may also contract for a security interest in the property sold in the subsequent sale as security for the previous debt if such debts are consolidated.
