Congrats on joining and pulling the trigger. I have bought many times with PureTime and they usually acknowledge the order and payment very quickly (typically within a day or 2). It could take longer to get your QC photos depending on your particular model’s availability. I have had experience from 3 days, to 3 weeks to get the initial set of QC photos.
It would be good to use the time to read up on typical QC issues with your particular factory/model on various forums. I found plenty of QC threads over on the r/RepTime subreddit. While they usually do a good job to screen out obvious flaws, you still want to look carefully to be sure there isn’t anything that bother you. If in doubt, you can ask them to take additional photos to see if the issue is really there or just due to angles/lighting effects.
Hope this helps!
