There is an error on this “$1/1 Sensodyne or ProNamel” toothpaste coupon from the 3/12 RedPlum.
The coupon barcode is specifically encoded only for Sensodyne ProNamel toothpaste. It will not work on other varieties of Sensodyne toothpaste. GlaxoSmithKline either should have used a broader family code in the coupon barcode or they should have simply written “Sensodyne ProNamel” and left out the “or.”
GSK has added the Sensodyne name to the ProNamel toothpaste line, and the image above is how the QSeer display will read after the next update. Note that GSK also neglected to put an expiration date in the coupon barcode.
We recommend that all manufacturers and coupon issuers use CHEQR. CHEQR is an iPad app designed as a quality control tool that enables brand managers and marketers to scan coupon barcodes prior to printing. It shows how the POS systems will interpret the barcode, and it contains a proprietary algorithm to identify errors and omissions such as missing expiration dates.
