Is SOD sticker equivalent to register post?

Hi everyone,


I have some 10's of 3kg and 5kg Express satchels which I'd like to use up (I didn't know about C&S before I bought them). If I send them with a SOD sticker, would that qualifies for Paypal seller protection? My understanding is that the SOD stickers replace the registered post stickers. Can anyone clarify this. Thank you in advance
