Lumber Liquidators has a deal going between 4/19 to 4/23, where they have priced Brazilian Cherry & Brazilian Koa of size 3/4" * 2-1/4" hardwood flooring at $3.69
Janka rating is 2350.
Janka ratinig is 2160.
These are very high numbers on the Janka scale which means that these are really hard to damage. Warranty mentioned is 100 years, a lot more than you'll find for other wooden planks.
Just for comparison sake, any OAK, Hickory, Walnut are soft as cake when compared with these.
I have been tracking for couple of months and these are normally above $5.50 so this is a really good price if you need it.
I'm heading to store too.
