For me, if estimating out of pocket costs, I take the higher of the two. If estimating
DDP savings, I take the lower of the two.* Neither site is particularly good about this, nor are they consistent with marking updates (if they update part of one, they tend to flag the whole restaurant as updated). Lastly, and what really drives me nuts, is there's no separation between standard and holiday pricing and minimal notation when/if the quoted price includes Tax.
Not that this little mini-rant helps you at all

, but at least it gives you a strategy if no one responds with the actual prices.
*Doing it this way essentially allows the planning of the "worst case", as paying the highest OOP or saving the least on DDP isn't the best case. If you spend less, or save more, that's a much better outcome than the reverse.
