Another Hogsmeade shop... How will I survive this?

Thomas lugged himself over to Dervish and Banges, he had a few more things on his list he needed to get, so he trudged along, wondering why the heck he got all this for them... He suppose it was because he loved them, and it wasn't as if he couldn't make the galleons back... Right? With that train of thought firmly established in his head, he entered the shop. "Hi!" He said cheerfully to the shopkeeper, once again nosing about the shelves, before putting the list on the counter. "Could you get all these for me please?" He asked her politely. "Oh! Would the Enchanted Mirrors only work in pairs, or could they work in groups?" He asked, if she didn't know how. Him and Sky could probably work on them, or they'd just keep them in the pairs and use them that way.

Gwen nodded and got the items,
"You´re Sky´s brother, right? Ehm...Tom? The mirrors will work in unlimited numbers. As long as the person you want to talk to has an enchanted mirror it´ll work." She asked counting it all again,
"Yep. 255Galleons please. You want me to giftwrap it?" She asked.
