An idea I've been rolling around in my head the last couple of days, but have been too tired or absentminded to post it, is in regards to banks potentially offering the services for deposit boxes and/or vaults.
The option for annual and bi-annual fees to maintain the box or vault, with boxes being an affordable route and vaults being somewhat more expensive (but offering greater storage).
Rough pitch of the breakdown:
- Small Box: Holds up to 5 items.
- Medium Box: Holds up to 15 items.
- Large Box: Holds up to 25 items.
- Vault: Holds up to 50 (or even 100) items.
Access to these could be done with a key or some other means. Personally I'm in favour of keys because it would be nice if they were used for something other than shopkeeping and offer a little bit of risk, as anyone with the key could collect the box and the contents therein.
Tired, so that's all I've got for now, but I'm sure there are a lot of potential ways this could be done. Perhaps have an option for items stored to have stasis, either by default or as a feature available for a surcharge.
