Frequently Asked Questions for Owens Corning FOAMULAR 400 (40 PSI) R-15 Extruded Polystyrene Foam Board Insulation, 3 in x 4 ft x 8 ft, Square Edge Sterling Black Q: Can I order a Pack Size:2 Pack

What should I clarify if an offer has location restrictions?

Ask whether the selected option is available in your circumstances. Do not treat a successful form submission as confirmed eligibility.

How should I interpret a seller's deadline when the time zone is unclear?

Distinguish submitting a request from receiving the seller's approval. Use the month name when requesting confirmation of an ambiguous date.

What should I do if a relevant policy link does not open?

Check any date or version information provided with the document. Do not substitute another buyer's recollection for the applicable written information.
