Don't I feel taken! Apple's App Store has it on sale for $7.99 after I just paid $9.99 to MacUpdate. Having problems using MacUpdate to get it installed. If I skip the MU install button and choose web install it brings up the Mac App Store. Hmm...
Gkwollum's comment on using the URL
did the trick for me.
So my bad for assuming Mac App Store pricing is always higher than MacUpdate's promo pricing. MacUpdate really should require vendors to offer them the lowest pricing during the promo.
As for the software...
i like the designs better than Mail Stationery Pro, but the customization is weak with the large graphics not being customizable. Mixed bag. Mixed Review. The plus for me is I like many of the designs. Just double click the ones you want and it'll prompt you to add them to a new email and to your Apple Mail's custom stationery directory.
