Suitable client login e-commerce plugin?

Hi – have just installed Woo e-commerce plugin and want to have the shop pages hidden from main menu.

Intended purpose is for clients to create a login area ( that they can distribute to friends / family). This will be used as part of a wedding list of wedding day photography products.

Friends & family will buy, whilst I have clean record of who bought what products for specific couple.

have briefly looked at S2 member – but looks a bit over complicated to use along side Woo.

Any easy to use suggestions would be greatly appreciated.

Thanks in advance – Linus
