A top favourite for buying domain names is 1and1.com, where the domain name can be purchased and other hosting options too. Alternatively, you can contact me to purchase it through my own reseller account if you feel uncomfortable with any of the steps involved with this process.

Buying the domain name at 1and1.com walks you through up-sell pages during the initial transaction. It is unnecessary to spend anything more than the initial purchase-price of the domain name, so you can skip past these up-sell items and proceed to the checkout to pay for the domain.
