A person comes up to you and says, "I can reverse time for just $1 per day." Do you take their offer? How far back do you go?

i.e. pay $5 to go back 5 days.

The time travel is permanent and one-way.

Edit: this is a one time offer and your budget is however much liquid cash you have right now. Cards are accepted, though.

For non-Americans, feel free to convert $1 USD to your currency
