can I order by phone and pay with my credit card. to be pick up at the curbside.

Call and check

No, you cannot make your payment over the phone. If you prefer to shop from home, I recommend that you use their app, or you can use any web browser and navigate to homedepot.com. When you're done shopping online, you'll be given the option to review the items in your shopping cart, and to select your preferred method for having your item(s) delivered. If all looks good, you'll tap "Checkout" to make your secure payment. Good Luck. ◉‿◉
