10x Nectar points on £10+ spend (Selected Accounts) @ eBay

I had to do this as well, thanks for sharing

Nectar points are worth 0.5p - spend in Sainsburys, convert to vouchers for eBay, and other options. Occasionally there are promotions that make them more valuable.

10 nectar points per £1 is 5%

When I check out item worth £142, I get "You will earn 1420 points". But with £547 item, it's only 3000 points. So it's worth splitting purchases to smaller amounts if possible. Unfortunately, I can't split set of 4 tyres, because individual prices is higher. (edited)

Massive clue. Pre loved

No the max is 3000

I wouldn't worry too much about it. I think eBay has linked the Pre-loved Fashion home page as it is well established. I believe the promotion is for "pre-loved", used or refurbished items. If the item you are interested in buying is included in the promotion, then the claimable bonus multiplier (x10) to a maximum of 3000 will be stated.

Me too

Should show at the last page of checkout (at least on browser, not sure if same in app) where you pick your payment method and address. It should be on the right-hand side with the price summary, underneath it should say "You'll earn xxxx Nectar points." where the xxxx should be the 10x amount if it qualified.
