Remember how we all wished that Hasbro would just sell their Kre-Ons without the so-so building sets that went with them? Well, now they are: but they're blind-bagged.
Fortunately, like the Mario Kart figures, the bags are marked to let you know what's inside.
None of us have found the little buggers yet, so this information comes from (friend of the site) JesterGoblin. As he discovered, the numbers across the bottom of the bags correspond to what's inside. Specifically, the last number. Here's the chart:
0 Crankstart
1 Scorponok
2 Waspinator
7 Spinster
8 Galvatron
9 Sunstorm

Now that Series 1 is out (the previous series was officially a "preview" of some sort), it's time to update the list. This time there's a number stamped across the top of the bag (on the back) and the last two numbers will tell you what's inside:
...40 Singe
...41 Inferno
...42 Springer
...43 Warpath
...44 Quickslinger
...45 Rampage
...46 Insecticon
...47 Blast Off
...48 Hook
...49 Dirge
...50 Airachnid
...51 Bludgeon
Series 2 apparently came out a while ago, though none of us have seen it. The top of the bags are blue this time. Here are the codes:
...66 Bulkhead
...67 Hardshell
...68 Blight
...69 Arcee
...70 Acid Wing
...71 Vehicon
...72 Scourge
...73 Powerglide
...74 Perceptor
...75 Lugnut
...76 Hoist
...77 Groove
Looks like Series 2 will never reach saturation, because Series 3 is out now. The strip at the top of the bags is green.
...50 Nosecone
...51 Thrust
...52 Nemesis Prime
...53 Ramjet
...54 Huffer
...55 Kickback
...56 Long Haul
...57 Guzzle
...58 Sharkticon
...59 Cheetor
...60 Beachcomber
...61 Seawing
Series 4 has a yellow strip at the top.
...33 Alpha Trion
...34 Barrage
...35 Brawn
...36 Cyclonus
...37 Demolishor
...38 Iceberg
...39 Kup
...40 Rhinox
...41 Rodimus
...42 Sandstorm
...43 Slipstrike (Slipstream)
...44 Breakneck (Wildrider)
Age of Extinction Series 1 has a red stripe.
...45 Skrapnel
...46 Fangwolf
...47 Misfire
...48 Trypticon
...49 Mindswipe
...50 Nightbeat
...51 Highbrow
...52 Jarugar
...53 Jetwash
...54 Wingspan Hawk
...55 Torosaur
...56 Silversnout
Good hunting!
I found these at Walmart near the Battleship Kre-O sets so you may want to check there. However, since then I've been to several different locations around Texas and have only found them once.
I've only seen them in my Toys R Us.
They even got a second box (... or just put it out later), since I couldn't find a Sunstorm the first time. The next time there were two boxes out.
Updated with Series 2.
