Every year, m/m romance specialty publisher Dreamspinner does this collection of daily themed stories for a month (technically, they do it twice a year because they've also an Xmas package, but that's beside the point), which they offer for a significant discount bundle price if you pre-order in advance.
2012 Daily Dose — Time is Eternity is the theme of this year's non-Xmas bundle, and offers you 31 short-story to novelette-length stories about m/m time-travel romances ranging from ancient history to the far future, mixed in with modernity.
You can see full author info and blurbs for each story in the product description @
Dreamspinner's webstore, where it's slated for release in June, with a new DRM-free MultiFormat title automatically added to your bookshelf every day, available worldwide and suitable for any ereader model.
The bundle is priced on a sliding scale of $39.99 if you pre-order it in April, $49.99 if you pre-order it in May, and $64.99 after that.
If you happen to catch it this month, it provides you with 31 stories for an average cost of $1.29 per story, and a considerable savings off the $97.20 list price of the individual stories combined. You couldn't get these any cheaper with a 60% off Fictionwise coupon, even if Dreamspinner distributed all their shorts to FW, which they don't (though if you are only interested in particular individual titles, longer novella+ stuff does seem to make it through).
If you happen to enjoy or want to try m/m romance, I'd say this provides rather good value for money, as it will allow you to sample a wide variety of authors, many of whom have longer-length works out from both Dreamspinner and elsewhere, for a rather low cost before you decide to buy any of their other stuff.
And I admit to being kind of tempted, even though I'm a no-romo. Time-travel of the non-romantic type is one of my favourite subgenre categories, and I like historicals as well, and some of the blurbs look positively cracktastic.

morbid curiosity, why must you tempt me so?! 
Eh, I'll probably break down and buy it anyway, just for that. I figure the publisher does DRM-free MultiFormat right off their website and offers occasional freebies (of which they've
recently released one I'll be posting shortly) and promo sales, which I want to encourage, even though I'm typically not interested in much of their romance-y output.
And it'll be nice to support an LGBT-friendly US-based company in a time when loudmouth bigots are vocally advocating the boycott of LGBT-friendly US-based companies such as Starbucks, Archie Comics, and JC Penney (and hilariously failing with their Facebook hate campaigns with a massively-outnumbering backlash of support in the other direction., but that's beside the point).
I've spent more money on junk food to worse effect, honestly.
