Have had experience of owning own business but not Post Office, it can be very rewarding but dont let anyone tell you it is easy IT IS NOT it is extremely hard work. Make sure you do all your homework find out as much as you can regarding profits, turnover, hours expected to be open etc. just because the shop is closed does not mean you have finished for the day, there is always paper work to be done. If you feel happy with everything then go for it and enjoy the experience, you will be well rewarded if you do it right. All the very best
