Any way to get free delivery on boden sale?

[pamelat]

I have already paid £12 in delivery charges and dont want to pay anymore.

I returned a jacket but want a smaller size. I didnt exchange but simply sent the other one back for a refund, so my fault.

Any free delivery codes?

nope, they never let you do free delivery on sale stuff.
if you hav a code it won't let you use it

Yes, agree you can't get free del of sale stuff. But you can get free returns by hanging onto the returns label they send with non sale items and then using it to return any unwanted sale stuff.
