Even if you can't make it to Comic-Con International, which officially kicks off this morning in San Diego, you can still enjoy some convention-sized savings, courtesy of a trio of sales:

• Top Shelf Productions is celebrating its 15th year at the convention with Cyber-Con, featuring digital editions of such new releases as The Underwater Welder by Jeff Lemire, American Elf 1999 by James Kochalka, and The Lovely Horrible Stuff by Eddie Campbell, and discounts on digital comics by creators appearing at Comic-Con. You can see the full list on the Top Shelf website; the sale ends Sunday.

• Fantagraphics, meanwhile, is holding its second annual Can't-Make-It-to-Comic-Con Sale, offering buyers a coupon code that will score them 20 percent off everything on the publisher's website, and 50 percent off its "biggest and heaviest books." The deal ends Sunday.

• And comiXology is offering its own Comic-Con special, with a half-price sale on digital editions of IDW Publishing's Godzilla comics.
