I purchased Sketchers lasso * on *.**.**. Ref **************. I was not told I needed the box to return this item. I realized at home that these were not comfortable and brought them back to the store yesterday. The manager informed me that he could not refund as there was no box. I was shocked as I had not been told I needed it for returning this product. I explained that I was not told at purchase about the box. The manager thensaid there was a notice behind the counter and also my receipt and I should have known. He was very adamant and I said I didn't even see the note behind him as the writing was so small. He then replied well you could have asked us to bring it over to you. Then said this was stated on the receipt. I replied that no one actually reads the small print at time of purchase. He still wasn't moving. I feel that he could have been more flexible as I have been a good customer and could have given me the return. I know you have policy's but because I wasn't told at the time I feel there should be some leeway. Perhaps you could also sort this out. Many thanks.*Address **-*A, Logwood Road, Newtownabbey.
