It seems like a more interesting approach to take advantage of price discrimination would be to execute 'persona swaps'. That is, if Amazon is offering me a microwave at $100 and offering you the same microwave for $120, could we digitally switch places so you could order the microwave at $100 if you wanted? A common method of e-retailer price discrimination is coupons so it'd be interesting to do real-time swaps in these situations too.
