Happens alot these days. Astropay were already Palaces training kit sponsor from last season and they were also Burnleys sleeve sponsor. Palaces new front of shirt sponsor is Cinch who also sponsor Spurs sleeves. The only time I really remember teams having the same sponsor in the old days was...
Don't ever need a third kit really if the colour of the away kit is in complete contrast with our home colours. We wore the away kit at Man City and Southampton when there was no clash and the white at Watford and Norwich so only the white kit was actually needed.
With the end of the season fast approaching we may be seeing the new kits soon. Castore have today released Rangers third kit for next season and there have been 2 leaks aswell, the new Villa Kits and Sevillas home home for 22-23.
To me the kits look like a fans knock up of what a hummel kit might look like. They may well be a hummel proposal for the club but I'm not convinced as they always use their other logo on Kits, not the chevron one.
Not Wolves but Rangers shirt for next season has apparently been leaked after some fans received them in the post by mistake. They ordered the "legends shirt" which was worn in a one off friendly a couple of weeks ago but received a totally different shirt to the one worn in the match.
