local pickup logic combined with sales taxes

For a local pickup as an option, in addition to shipping, will MarketKing correctly computes sales taxes based on the vendor store location? In the US, each state has different sales tax rules, each city within a state may have multiple sales tax rates; further, there are food and non-food sales tax rates that are different. So the location of a store will determine the sales rates which may be different than the destination sales tax rates if product is shipped. I am planning to switch from Dokan to your product, but I need to do my due diligence before I plunge and encounter similar issues with your product. 

Thanks,

this is very basic feature why is it not provided or developed? Local pickup is very common feature of all ecommerce stores big and small, unless sales tax rates are correctly computed based on the store location, for local pickup, I am finding it very odd that you have US customers because every one will need this feature if they offer local pickup. 

Also, if you implement this feature, think of the advantage you will have over your competitor. Your pricing is already better than Dokan and I will promote your product every where I post on social media. I will be your advocate :)
