I can assure you that he is basically right. One sale is to kick off summer, the other is for the holiday season. Has been like that for a few years that I bought things from DDD. So give or take, june-july, and november months.
All I know is I remember it always being end of June to early July, since I never had enough money around then. And they called it 'summer sale' all of the times I participated in it, so I don't know if they going to change it for this year. Aswell as the later sale has a turkey on its banner, so, thats end of november All I hope is that certain companies don't back out like they did this year *cough ADV cough*. I missed out on so much
Then don't post in them. I, personally, was glad to find this thread since I'm out of the country and haven't been able to keep track of when the sales are lately.
