The McChronicles combined two McDonald's Arch Cards today. It went off without a hitch.
First we asked the crew person if this was possible (we'd heard it was - wanted to see if they were confident of the fact). They were 90% sure it would work.
We gave them one of those free $1 cards from Christmas - it worked - then our regular Arch Card. We all watched with expectation until it, too, worked its magic.
The receipt told us that card #1 was empty and that card #2 still had a balance available.
