[Question]: Humble Bundle Summer Sale??

There should have been, but apparently this is not the case this year. Eventually gave up and bought my only wishlist item from there at some other store which had a discount on it.

if im not totally wrong, i remember it was about 1,5 month ago. so you missed it.

There was a spring sale that ran most of May. In the past, they've had a summer/end of summer sale late August/early September, iirc.

Edit:
Sources: subscriber emails:
"Grab Dungeons 2 for FREE and save on thousands of games in our Spring Sale!" May 11 2017
"Tropico 4 is free to kick off the Humble Store's Summer Sale!" September 8 2016
"The End of Summer Sale begins with a FREE game" August 28 2015

If last year's sale is any indication, it's a month away.

In addition to the spring sale that others have mentioned, there was a DRM-Free sale in the beginning of July, just as the Steam summer sale was finishing up.

The past couple years Humble has also had an "end of summer" sale, which usually starts last week of August/first week of September.
