To make it worth the wait, I've discounted all specialty shop items and added an option for rare items to rotated out periodically.
I did it this way because I really wanted buying ingredients to feel like other farming sims where you would get supplies from different types of shops during normal business hours.
These specialty shops carry items but are only open certain days a week and some shops only carry seasonal items. There are several different shops you can call to receive deliveries from, each specializing in certain types of ingredients.
This mod includes 'Brazen Delivery', a store-to-home delivery service that your sim can access from their phone.
