I bought this and was thinking about the interest generated in a different thread. These are inexpensive.
Disclaimer; I am not this seller nor do I know them personally, I've just bought from them and been happy.

There is also another seller with 100 cubes for $26.99 OBO

Not bad Tami. But I did find a 100 lot on Amazon for 24.44 shipping included.

Rafed, looks like you should have invested in the Root Riot company before you started posting about this ;-) . I just rec'd my 100 ct in the mail today. I don't remember you warning us about how these things smell! Phew! I thought for sure they contained cow manure. Not so according to the ingredients though.

The cubes in the Root Riot I believe are Oasis cubes.  I wouldn't mind trying them, but the rooting season is almost at it's end.

Noss.  Guess I should have looked at that listing before posting :-/ .  $21.00 shipped is a good price. Looks like I should have shopped eBay first.
Seller name I got mine from on Amazon is "GreatDealsNow". Shipped on the 13th - arrived today.

I also ordered a 100ml bottle of Clonex (from a different seller). I look forward to seeing how well this combination works.

Hey Dan. As long as you have dormant wood to work with, it's never really "too late" to root stuff if you're in the mood. You just have to adjust your acclimation techniques when adjusting plants that have been rooted indoors. Once they're well rooted, a shady porch has worked well for me when it's hot outside. I then try to give them a more "sunny" spot on an overcast day in an effort to acclimate them. I then might keep them under a shade tree for most of the summer if need be.  Gradual acclimation seems to be key here. 

Then there's propagation of growing wood in early summer too. I've not done this yet but I hear it's much easier than dormant wood.
