The computers settings and the pegs haven't transitioned together. I'm hearing about this all over the place. The publicly shown price is the price though... It's false advertising otherwise, and you'd have a gripe WAY beyond the service desk if they tried saying "welp, you gotta pay $5.88".
That's a bigtime no-no, and could be argued as false advertising (or simply, lying), or "bait & switch" selling in a way.
They just don't have their crap together though, that's all.
