Filofax as a wallet?

Which Filofax works best as a wallet? It is a question I often see being asked.

However, someones comments recently got me thinking again about it from another point of view.

So what do you need when you are shopping?

• Money
• Credit cards, Bank cards
• Store cards 
• Shopping list
• Short list of essential phone numbers (optional if these are all on your mobile phone) 
• May be a monthly planner or year planner
• A few sheets of note paper may be. 

But does your 'wallet' Filofax need to be your planner as well? 

After the discussion recently I reached a conclusion that may be it shouldn't be..... why? As a wallet you want your organiser to be small enough to put in your pocket or in your bag. As a planner a lot of us need more space possibly. And obviously using an A5 as a wallet isn't going to look too cool at the check out? But it is an ideal size as a desk planner. 

Is personal size an ideal compromise? May be but unless you have some big pockets... or you carry your organiser in your handbag/purse or man bag, you have to carry it in your hand, not ideal when emptying your basket on to the check out? 

If you are going shopping do you need to carry all of your planner, information, addresses etc in your main planner with you? If a friend does meet you whilst at the shops and asks if you are available for coffee next week, you could have a facsimile of your calendar on a monthly or yearly calendar in your 'wallet' Filofax, or simply take a note of the details and offer to ring back when you get home? 

So may be an A5 or Personal for home use and a pocket or mini for shopping?  Personally I would favour a small ring pocket, slightly slimmer, 15mm rings would be more than big enough I'm sure. Credit card pockets are available in pocket size too, although I know people do make their own for mini size. 

See my video below from a few years ago, about using a personal size and pocket size Malden as a wallet.

What about you, what would your ideal solution be?
