Sorry, to post again so soon, they also replied to someone's comment on Facebook that a lot of the recent samples (Johnny Chimpo, Fruity Hoops, etc.) that they plan to put on the site will likely be on by the end of the week, so probably in with the Thursday 4th of July sale.
If you're looking to try similar liquid from MBV, you could try banana fosters or bananas gone nuts if banana is your thing. If you like the maple, you may like sticky bun. I literally just placed an order for it, but I've heard good things.
