I sent a trade with lots of pets and items on your wishlist for coins. I did the math since it was such a large trade, but feel free to check me. 3380 coins This will also be a large purchase as well, so I added all of it up and then found my balance of coins after the purchase. These can be found below the purchase.
Once that trade is accepted and I have some coins, I would like to upgrade the Sigbox Marci is in to a medium beach. I would also like to buy a large field box and a large forest box. (700 coins)
I would like to buy a potion of exploration, occurrence, love, and fertility. (One of each, but I don't want to use any of them yet.) (400 coins)
And last of all, I would like to buy a panda bear stuffed animal for Marci. :3 (20 coins)
When you put all of these together, the total number of coins spent adds up to 1120 coins. After this purchase, my balance will be 2260 coins. Hope this helps out a little, I know you're pretty busy with this adoption center, so I felt like I should at least save you some time, since this was such a large order.
