Buying Cigarettes Online sometimes make a headache. Lack of Payment Gateway system, that refuse a transaction for Tobacco/Cigarettes related products. If we choose PayPal as our payment gateway, for sure you will risk being banned/permanently limited account by PayPal because of violating their TOS.
Credit Card Payment gateway is common and most used for Internet Transactions. But, we back to PayPal case, when some Credit Card Processor refuses us to be their merchants because Tobacco/Cigarette business are strictly regulated.
But, we still have the option to do the smooth transactions with Credit/Debit card directly.
