I received a refund

I feel guilty, I received a refund for an online purchase as well as my stuff!!

I don't know what to do, about 20 days I purchased a book at abebooks.uk. The estimated delivery date was about October 7. However, it was already Oct 11 and I had no news about it, so I decided to request a refund. Today I received my stuff early, as well as the refund I had asked to be issued 2 days ago. What should I do ? Should I tell the seller that I received my book after all, and give him the money back (de-refund)? Please, tell me what to do, I know it's unethical to do so.

Though, I'm also aware it's not completely my fault, and it's kind of my right to be refunded. Like the pizzas slogan "15 minutes or it0s free2. Plus those companies do not lose money either, do they ? I guess it's not such a big deal for them. Bu yet, I feel guilty, because Abebooks is a site for independent seller, and this kind of things do affect them and make them lose money. Do you think it's so bad to keep both, the money and the book ? I feel terribly guilty.

Shopping Alone

Because of how bad I have been feeling. I thought of going out to do my shopping alone.I called Hiro when I got to the train station. I heard the disappointment in his voice. being he worries about me more now. So,I went to buy my daughters stuff and buy my shirts. I was happy to find them for $3.99 instead of the $7.99 I saw them for early in the month. I bought about 5 of them. Then i bought 2 packs of panties and one pair of sweat pants. also about 7 pairs of socks and then one pack of solid black socks.

I sat in a pizza place and took 4 bites of my huge slice and felt funny. I tossed it out and left. I was walking slow and easy. trying to not get dizzy. I went to the train and then hopped in a cab to go home. I have to go shopping with my neighbor to a new store. so I put $40 a side for that. I like buying clothes on sale. I hope your day was swell today.. did you go shopping?
