Hi Jan,
Say for example you bought an item from me in the UK, and wanted it sent surface mail. How would you feel about getting a feedback reminder after 30 days, when the package could take up to 12 weeks to arrive?
Surface mail is getting more popular now because of the cost savings.
I posted one off a couple of days ago to a new member with no feedbacks. What is he going to think if he starts getting feedback reminders weeks before he even gets the product.
