From memory - (apologies if this is not one hundred percent correct; as I have forgotten certain details, due to not familiar with this company) - I have only bought with OnBuy.com the once.

Ordering the dvd was simple and straightforward, and I would by from them again.

Personally, to properly review OnBuy.com would not only require another purchase from them, I would also need to note my experience shopping on the site and note the receipt sent via email (the original receipt was delated when I received the item ordered). Thus would give me a much more thoroughly comprehensive (read accurate) review of OnBuy.com. Until then...
