Bivouac in NZ are having their sale again. Once again they have the Exped Synmat UL 7 Medium at NZ$116. xe.com suggests this is around US$95. Shipping to the US is $20, BUT if you spend over NZ$200 (ie buy two mats) shipping is free.

This is a great price from a company that have always given me great service. (no affiliation)

I have posted a very similar thread to this previously, which a few members took advantage of.
