Hello for those who have experience with locabitcoins.com , what happens if you place a buy online by cash deposit order at night from a seller whose payment window is 180 minutes when the bank is closed?   I've been watching seller ads for the past few days and would like to order from one of them but it's night now and of course can't get to a bank within 3 hours since the branches are closed.
I am afraid that if I wait until the morning, the seller will either run out of btc or his/her asking price will be too high.

Another question: There is one seller whose prices I've been watching, they are low now, the profile shows  he/she is "on vacation" but I have their celll phone number.  I don't want to be rude and wake them up but I really want to get a good deal, so what what would you suggest I text him/her to convince them to sell me some coins?
