Giving a little bit extra in Spain

I've thought for some time now, that the Spanish tourist authorities should use the strapline "Spain - where we like to give you a little extra". It could be the free snack or tapa with your drink, or the wrapping service that comes when you buy a gift, as many service businesses in Spain like to compete by offering a little extra.
It's something that I think about all the time, as regards persuading people to come into the bookstore, rather than just ordering books online (we also sell via Amazon marketplace). We've had a free Mince Pie promotion before Christmas, and also free posters.
Currently we give away free book bags (some of which are from Daunt Books in London) when people spend 10 euros or more in the shop. So far the reaction has been very good when this has happened, and customers have promised to come back to the store. Whether they do or not obviously remains to be seen.
I intend to have a new promotion later this week, that will stagger other bookshops in this city. I can't release more information at this point (as competitors may try and jump in and spoil the promotion, or the co-operating party pulls out) but it will be available to anyone buying books in the store, even the 1 euro bargain books. Watch this space!
