Yes, the product will show the name of what it is. Spackle will normally be in the painting department, joint compound will be found in the drywall area. If you a lucky to find someone in the paint department who has a clue he could direct you but that is very ify!!!!!!!!!!!!
If you post your need here on the forum you will get the RIGHT information on weather you need Spackle or Joint Compound since they are totally different products and do different jobs.
