If you are using a drop to prevent automated checks, misspelling your address normally does the trick. E.g. if your address is 88 Station road AA1 1AA, you can type in 88 stacion road, AA11 1AA. The mailing service will guess the right postcode for you, given that you live in a small town and you specify the town. I wouldn't risk this trick if you live in a city though.

I usually “accidentally” put the wrong address. So if I live at number 4, I address the parcel to number 44. Then on the day after it’s been delivered go and tell them (number 44) I realised today I accidentally put 44 instead of 4. Works with any number on your road really

I wouldn't bring in the innocents. Your neighbor doesn't deserve to get billed.
