You need to check the schedule.As nobody has answered this question that they have been checked by AMET, either in this thread or the other one, I assume nobody has and that the whole panic to buy these items was just a scam to get gringos to part with their cash!
Like every Tuesday is helmet law day
Alternate Wednesdays are red light and stop sign days
Thursdays are one way street days
And I believe the new first aid kit/triangle/fire ext. days are the last Tuesday of each month
