Definitely need:
good attitude to customers
the service of responsible storage
a normal personal account
cash services
want to be able to know the balance of goods in stock (ideally in the personal Cabinet)
already using one of the services, but a lot of criticism. Maybe there's already a decent player in this market?
UPD. I confess. I forgot — talking about Moscow (although the ability to deliver to Peter and the other millionaires too).
