I’ve recently started shipping all orders via express airmail. I had been relying on surface mail until recently, but the service was very slow and also prone to delays. Using express airmail, is significantly more expensive, but takes only a few days to deliver. The price of these services will unfortunately go up next month. I don’t want to raise my own prices. So, to help offset the extra costs, I’ve created a voluntary shipping fee. If you’ve made a purchase or are planning to make a purchase and can spare a little more to help me pay for the increased shipping costs, it would be greatly appreciated. Again, this fee is purely voluntary. Everyone will be receiving their orders via express airmail.
