Help me find baking powder please

[ODFOx]

I'm buying for an elderly couple. She is quite confused but loves to bake and has a weekly routine. I need to get baking powder before the weekend so she can make scones on Sunday ( probably inedible but following the recipe is important for her) . Major supermarkets have failed me. Suggestions please!! TIA

I got some from Aldi at the weekend. We also have a local butcher, local farm shop and a cake supplier all saying they have these bits, worth making some calls if you have anything similar? I also found a recipe VE weekend that didn't require baking powder, also an option? Obviously didn't rise as high but once the jam and cream went on, couldn't tell!!!

Amazon seem to have at varying prices.

Local smaller stores haven't had any in months around here but DH went to a big Aldi store on the edge of city he works in and they had baking powder and self raising flour. Or local M&S was getting small amounts of self raising flour. Or they have some baking powder in stock on Amazon for a very inflated price.

I got some in Waitrose recently

In my area local independent bakers have been selling baking ingredients like flour, baking powder etc. Might be worth asking.
