Christmas LED Lights Bulk

Considering doing this when the season comes up and I wanted to stock up on supplies. I figure what better time to save on Christmas lights then in the middle of the Summer when temperatures are starting to peak in the 100’s, well at least here in Texas.

I know LED is the way to go but other then that I do not know much. Can anyone recommend a good supplier?

Any pointers and tips would be helpful, regards.
