I can help you . Points.com is an affiliate partner and using Commission Junction. So, if a blogger suggest buying points, he might have and affiliate link to this page. And they do not offer cash back. Looking forward to read your blog

On a more serious note, my hotel in Florida in August (IC Miami and IC Miami Dorval) became cheaper after the devaluation ... Not much (2k points) but nevertheless. And I think, that some less uspcale hotels are also cheaper (the HIX Düsseldorf Hauptbahnhof and HIX Düsseldorf North which I checked recently and on a shorter notice). London for sure became more expensive and also on dates I checked the IC Barcelona. And in favour of any blogger, there are still some hotels on specific dates, where it can be cheaper to buy points instead of a cash rate. Do not forget, that you can cancel a points booking in most case till the day before arrival.
