Evri prices via Amazon are very cheap. Can I use these services?

I usually post everything via Royal Mail Medium Parcel (3.5kg) and it’s about £6.59 for Tracked 48.

I’ve just noticed that if I buy a label for Evri through Amazon, I’m getting a super low price of £3.24 for 2 day delivery. However there are multiple prices for drop off and standard. Oddly, standard is cheaper than drop-off? I was able to drop off the parcel at an InPost locker for the “standard” price.

There’s also a notice underneath that I need an account with Evri. I have an online account, not like an official business account but a standard account for buying labels which would normally cost a lot more through their website. The link takes me to a van collection application form.

Question is basically, am I able to use the “Standard” option for parcels going forward and drop them off myself? I was able to once, and the parcel on Amazon says “Waiting for collection”.
