Can anyone tell me if my S&L item fees are correct please?

Can anyone tell me if my S&L item fees are correct please? Its the first time I’ve enrolled any SKU’s into the S&L scheme. I successfully enrolled 25 SKU’s which are currently being ‘received’ into the fulfilment centre. Currently the fees on my inventory page are - £9 item / £2.70 fee which includes 86p FBA fee - does this seem correct as that doesn’t seem much different from my ‘normal’ FBA fees? BTW the SKU’s are 50gr / 1.8cm H / 17cm x 14xcm, so should qualify for S&L.
Any input anyone please?
