Things change over time and the stores may introduce new products or discontinue others, so ultimately knowing a specific store won't help much to people around the world.
I'd usually check some online store or a local vegan website with recommendations on stores. Some of them may be far away but worth checking :)
I know you did not ask for recipe, but as an alternative, making your own 'ladyfingers' biscuits may still be a good idea and shouldn't be a very big effort.
When baking, eggs can be replaced by using things such 'aquafaba', chickpea flower or 'flax eggs' (made of ground flex seeds and water).
