hobby lobby registers are not set up with a database. they dont use barcodes. the cashiers only know the price when it has a sticker on it. the only sales they know about is the newspaper ad they have plastered to the registers booth.
Which is great for us consumers until the person in front of you REALLY wants that picture frame but somehow managed to get the last one and the price tag is missing, resulting in a long wait at the only open register!
If they ever go to scanning barcodes, it will mean the end of great deals as I have lucked out a few times with current kits having clearance tags and getting them for 50% off, sometimes more!
