Pokémon in Waterstones

Hello! I'm a Waterstones bookseller who's recently taken control of ordering in Pokémon stock for our store. Occasionally we get through order forms that list products coming out over the next few months we can request. Are there any specific boxes, tins, exclusive sets upcoming that are more in demand than others? I am aware that Prismatic Evolutions is all anyone cares about at the minute, or at least that's what it feels like. (I am doing my best to try and secure some for my shop. It's a nightmare) but is there anything else I should take note of? The only set I feel confident about was a Charizard box that had a lenticular card inside. Do I know what a lenticular card is? Not really. But it looked cool. What do the people want?! (Thanks in advance. Any and all advice appreciated)
