We crossed at Nogales and turned in our tip at km 21 midday on Monday. As of this morning no refund yet. In the past has shown up the next day as it is supposed to. Anyone else experience this?
Yeah, what Scorpion said, give it a few more days. Last year ours showed up in 4 or 5 days, don't remember exactly. This year of course we didn't have one to turn in. :M
