I have a $110 limit on my account each day. I bought a few things online over the course of 2 days, the first day totaled $90, the second day was $50. They all showed up on my account a few days later on the same day bringing the total to $140, $30 over my limit. Well I was trying to get one last thing but it said that my account had a security hold on it.

I was wondering if that happens, is that the reason there is a hold on my account?

Probably, if/since it says they all went through that day and made you reach your limit that day.

So, even if I buy stuff separate days, but they all go through the bank on a different day but all the same day, that counts as my limit which will trigger the account hold?

Or is there another reason?

They all went through on one day, even thugh they were made on different days, sometimes it takes time.

If there was another reason for a checking account hold, you would've been notified.
