Just wanted to share something here. I had previously seen auctions that stated "no eCheck" before, but I didn't know what it meant. I recently received payment by eCheck and apparently it takes 3 days for an eCheck to clear. I went ahead and shipped the eggs, trusting the member here, but in the future, I will be adding "no eCheck" to auctions also, unless they want to wait 3 days for the eggs to be shipped.
I accidentally paid for something with an eCheck once, through Paypal. Didn't know that's what I was doing until it was done. It happened because I hadn't yet linked my bank account to Paypal, and it didn't tell me anywhere in the process that it would take a few days to go through, though that may have changed since I did this a couple years ago. Luckily it wasn't eggs, but I was still frustrated with the delay I caused myself in receiving my stuff. To stop this from happening, you need to link your bank account to Paypal if you want to use it to pay.
