Bit late to the party, but just wanted to mention the products I rate.
I was a bit sceptical about the BP concept at first, but really like it. I have the £5/month subscription and just let my credit build up for a few months and then buy a pile of a stuff.
I've definitely had more hits than misses and really rate the following:
Wondergloss Lip Oil - as good as if not better than Clarins Lip Oil
Wondercolour Eye Shadow Sticks - brilliant, dupe for Laura Mercier and Nudestix and miles cheaper.
Lip Balm Sticks especially Sexy Berry, Baby Bare
Healthy Skin Body Creme - I don't love the scent (everyone else seems to rave about it though), but a fantastic product
Soul Provider Relaxing Shower Oil - divine
Retinol Hand Cream - amazing stuff.
Make Up Brushes - I've replaced all of mine with BP brushes, excellent quality
Cleansing Cloths - definitely buy, cheap and very effective
Nail Polish - brilliant, especially the dark red and nudes.
The only products I didn't particularly like were the matte lipsticks and the triple hyluronic acid serum (although I seem to be the only person in the world who doesn't like the serum).
Hope this helps!
