I'm a big fan of Original Source shower gel. Not always much choice in store & sells for anything up to £2:25 a bottle.
Supadrug do online shopping & like Toolsatan, free delivery on orders over £10.
Got my favourite 'flavours'- 3 x Black Mint, 4 x Chilli & Black Pepper and 2 x Pink Grapefruit all at 99p each & two aerosols of deodorant all for £10:98 delivered free.
Well worth a look.
