Will I be able to find these things at Boots, Sainsburys, etc?

Ditto.  I always come back with hair care products, make-up/skin care, venus razor blades, dial antibacterial soap, and hand soap from Bath & Body Works!

I do this as well I am a Bath & Body Works junkie.   I started using this new line of Herbal Essences shampoo & conditioner while we were home. I liked it so I brought back a few huge bottles of each of them with me. Aussie hair gel & mousse for DH & I. we also bought dh's skincare products back home. they were almost half price for what we pay for them here so we stocked up on them majorly.
