Next time in the bookshop

It has been nearly a month since I have been to the local bookshop and I have not spend yet the voucher I had earned. I walked in front of it at least twice recently, but we had other things to do, so did not have time to stop. I would rather go there when I have plenty of free time to spend there, so I can explore the bookshelves at leisure and find the book I need. I say need because when you discover a book you want... you know you now need it. So anyway, I need to plan my next visit to the local bookshop and go there soon, because it will have been at least a month when I go there and it's long overdue.
