I bought a digital photo frame from this bunch and have just found out that I have been paying £19.95 a month, every month, from last October, after failing to "untick" a box to say I didn't want to be a member of the site, and, consequently, after "a month's free trial" I inadvertantly became a full member and have been billed this said amount, I only noticed on this month's statement.
Beware of these, and others like them... I am appalled...
