Time to reply to offers - eBay contradicting itself!

eBay says you have 48 hours or until the end of a listing to respond to an offer yet messages me to say an offer has ended as it's only valid for 24 hours!

 

"What you need to know After receiving an offer, you have 48 hours to respond to the buyer."

it's up to 48 hours,

 

 

the person making the offer can change the time scale

 

it will tell you on the offer how long you have to respond
