Where are you trying to update the expiration date? If your card itself has an expiration date that needs updated, your bank will usually issue you a new one, with a new expiration date automatically before your old one expires. If you are talking about an online store, you will need to login to the store with your e-mail address and password, click on payment methods or cards on file (depending on the store) and then edit the payment method.

It would help if you mentioned where you were trying to update the date. Your question does not give much information to go on.

The expiration date is usually six years after manufacture (not first use). An expiration date may be embossed into the back or bottom of the plastic shell.

Most car seats have a six year expiration from the date of manufacture (not first use). Some seats may have an expiration date on a label, or may have an expiration date embossed into the plastic. To be certain, call the manufacturer. In the USA, call 800-544-1108 (Dorel Juvenile Group).
There are several recalls on the 22-150 model. See www.carseat.org and click on "recalls."

The detection of Hollister coupons is really simple, each of the promotion code maintains its expire and validation date, therefore if there is not mentioned the expire date or the reason for not mentioning the expire date, it is best to know that the promotion code could be useless, but without doubts the reputation of the website you are located is highly important. There may be not mentioned the expire date, but still you exactly know that the website is highly trusty. Thus without the researches we're capable of getting the money off coupons by using coupon toolbars
