Based on several posts on the forums, it seems that Pinbits.com has become fully unresponsive since late 2020 or thereabouts. The latest website news update was from May 2020. Various individuals have reported that their website still accepts orders, but items have not been shipped, nor have they received responses from email or phone inquires.
If you have not received your order or a response from them, it seems the recommended approach is to file a paypal dispute.
Until pinbits starts responding again, it might be wise to avoid ordering from them from the time being.
On a personal note, I hope Pam and Martin are doing well. They have provided the community with a lot of nice products over the years. If anyone happens to hear from them, I'm sure everyone would be interested to know how they're doing.
