Truly Thrift verifies Professor Whyte’s codes through a three-layer system: automated checkout testing, cross-source corroboration, and real shopper reports. Verified codes show a green badge; other codes show their recent chance of working. Code health is a per-code reliability score built from that evidence — right now the 6 codes listed for Professor Whyte’s carry an average code health of 78%. Read our full verification process for details across every store.
Direct checkout testing currently covers Shopify storefronts, with more platforms rolling out over time. Until Professor Whyte’s is covered, Layers 2 and 3 below carry more of the weight for this store's codes.
For codes we can't test directly, we check whether independent coupon listings still show the same code as active. If independent sources agree a code is gone, we downgrade or hide it — even before a shopper reports back.
Every "Worked" / "Failed" button on this page feeds straight into these codes' scores. No shopper reports have come in for Professor Whyte’s this week yet — yours would be the first.
