If this were to become popular what would stop someone from building something to do the reverse of this, e.g. see if the item could be cheaper if you bought it as another customer/from another device/computer/location?
Yeah, someone could totally build Honey for [name-redacted] if they really wanted to here haha. If you think about it, discounts that don't apply to everyone (what Honey targets) are pretty much unorganized price a/b testing.
That's probably a good problem to have! Nonetheless, customers are still buying from the same store, so, it's a win-win. Breaking customer trust is probably the only thing that's bad here.
Yeah, it's a tradeoff for sure. I would say discounts that don't apply to everyone are a less organized way of a/b testing price. So a brand that does discounts all the time on certain cohorts of their users is going to have an easier time swapping over to using [name-redacted] vs. a brand that has 1 price, no discounts ever, never have changed their price.
