This does happen quite frequently if you pay with a debit card, however although a similar hold is used for a credit card, as long as the hold amount is below the available balance, it does not affect your ability to use the card.
This is one of the many benefits of using a credit card, but of course does need you to exercise restraint and not to over spend.
PS it will disappear within a month, but of course it can be very inconvenient at the time
