Your product schema is probably fine. Your product identifier probably isn't.

An analysis of 100 WooCommerce stores revealed that while 72% of accessible pages utilized Product structured data, most lacked critical product identifiers. Only 4 of 76 pages included a GTIN or MPN, and 51 of 55 stores with structured data omitted identifiers entirely. Separately, Amazon Prime Big Deal Days is concluding, with remaining offers including $200 off MacBooks, 53% off Bose headphones, and $1,200 off Samsung TVs among other live discounts.
