Me!
I can keep all my cards in it. I have one set of my cards I use all the time, credit, debit, supermarket loyalty card, and one set for membership cards, other bank accounts. Licence, E1-11 etc. I am never without a useful card.
I have room for cash, receipts, vouchers, tokens. I get out a lot of cash every two weeks to pay service providers. Coins too, always useful when you have a child and want to go to a school event.
I have room for other things, a house key, pain killers, earrings or other miscellany I don't want to lose whilst out.
Not only do I have room to carry all the things I might need, I can also find the thing in my (also large) bag. And as I have a Ted Baker matinee purse it is bright and shiny which helps even further.
It's a thought saving thing for me. I will go out for the evening with just a card and my phone but on a daily basis I have my big mummy purse. It's shiny and pretty and a bit sparkly and it makes me happy.

I also get mine cheap from eBay.
