Weekly deal? Which day does it change? Question about a wavy border on hexagon shape

[cathym]

I noticed the weekly deal had the Malam batik charm packs on sale earlier this week and to save on shipping, I decided I'd wait to order until I saw the rest of the deals this week. Today, they aren't on sale any more. Which day do the weekly deals change?

Second question...I finished the top for a Christmas tree skirt, but a couple of the outer wide borders on the hexagon shape are a little wavy. I tried to avoid that by pinning and measuring, but due to the shape, it was a bit hard to figure out how long they should be, so I just used the outer measurement. Any hints on doing this type border?
