She wasn't entirely sure who would sell these items, which were much more rare and specialized than typical general stores would have. As she hobbled around the southern portion of Crater, where much of the stores were, she kept her eye out for anyone who looked like they sold more than just travel goods or basic Pokemon supplies.
Moving toward a shopkeeper who looked promising, Cynth gave a friendly smile and greeting, before getting onto her business. She was shopping on her lunch break, after all, and had a limited time to get back to Agata's. Plus, this was a busy time for other shoppers, as well, and she didn't want to be in anyone's way if she could help it.
"I'm looking for a Pokedex or a Lucky Egg. Do you happen to have either of those in stock?" If the answer happened to be yes, Cynth would then continue: "I have a half-price voucher, and I have a couple of items I can trade. Mainly, I'm interested in trading this Focus Sash. And I can make up the difference in tokens, as well."
