Hi 24266353, if that's your real name! 
I would think sale or return would be best in the current climate and it's probably more likely that you will get space in the shops.
If you do go that route I would have the retailer sign or accept conditions that state the goods will be returned in their original state and if any are stolen/damaged they have to pay for them. Maybe give 1 or 2 for display purposes that will stay your property so you can remove/change at any time.
I would sell them SOR at a higher price as well because you are taking all the risks. I would think about £10-£12 wholesale but they would need to put more on than your £17.50, so it might be best to increase the RRP on your website so they can sell for say £20-£24. That would be the price they would pay wholesale on ordering, but sale or return I would add a few pounds to cover your risks. Don't take too many either, you don't want all your stock sat in their shops. If they are local you can call in once a week to replace the goods and collect payment.
You could also mention that you would put their details on your site as a preferred supplier of your goods and maybe get a window sticker done for the shop. Free advertising.
Hope it goes well. Where in the Uk are you?
