Did you have any way of identifying who hit you (witnesses, cameras, notes, etc.)?
Do you have insurance?
Typically, the other driver would be at fault
Contact their company to file your claim, and they should pay for your repairs. If they don't have insurance, and you can't get them to pay out of pocket, you can instead file a claim with your insurance company.
If the other driver is not around, head back into the store to see if they will allow you to check the security camera footage. Also, be sure to take pictures.
Sorry, but you'll have to pay out-of-pocket for this one

Case closed: You're likely covered
As long as you have collision, you're covered. Most drivers have collision, and you can find your coverages info in your online insurance account or in your policy documents. If you don't have collision, uninsured motorist property damage can also cover this accident. But this coverage is not offered in every state, and in some states it won't apply if the driver is unidentified.
Next up: File a claim with your insurer. Keep in mind, you may have to pay your deductible.
A deductible is the amount you pay if you have an accident or claim. For example: If you have a $500 deductible and $1,000 in damage—you pay $500, and your insurer will pay the rest.
