Service not that great. Save your $ – Sandboxx Review

I have been paying attention to the dates delivered. On average, the letters I write and send in regular USPS mail are arriving before the letters from Sandboxx and I got charged twice for the same letter that was sent twice a week apart. This would be a good service if they did what they said but they don’t. It’s just as fast to send through the mail and costs a lot less.
