E-Cig 101 accepts all major credit and debit cards for online transactions. Credit card information must be manually entered for each separate transaction, as we do not store or keep credit card information on file. E-Cig 101 gift cards can only be purchased and redeemed in-store at this time. All products sold are listed in US dollars. Payments cannot be split between multiple credit or debit cards. All credit and debit cards must have a valid security code.
