I agree. Communication is key.
However, just a warning to anybody considering to join the group buy. Waldo will absolutely not give anybody a refund. I tried backing out a few hours after sending a payment and he refused. He should've mentioned it in the original post but instead he fails to disclose it.
Also I've messaged him yesterday and he has still yet to respond. If there is a better way to keep in contact with you waldo, please let me know. The untimely responses make your group buyers extremely frustrated.
Fellow group buyers, let's keep in touch.
