Not everyone uses the favourite stores feature. At current the mailing list feature
is available to buyers when they add a store to their favourites.
I propose that the future `refurb` to the site seperates the two features and
makes the contact list feature available independently and more prominantly...
Perhaps it could slot in somewhere on the checkout screen or maybe the order
confirmation screen.
`you have placed your order #1234567, would you like to subscribe to #storename
mailing list?`
This sort of message could also be optional from store settings so that only
stores who use the mailing list function will have the option visible to buyers.
I believe making this feature more visible to buyers who may want to use it means
they are more likely to find it and thus use it, which will lead to better repeat
customer rates and help retain custom on bricklink as a whole.
