What is the right way of adding jquery to the page? There is no "right" way. All depends on what you want to achieve or avoid. For example, SFRA exposes jQuery at the very beginning of JS execution like: window.jQuery = window.$ = require('jquery'); In that way, you have access to $ in any code you execute below without adding additional bundling mechanisms. The drawback is that you "ban" jQuery and $ names globally for yourself and should always remember it, especially when you use 3-rd party scripts, just controlling (while you can't do it fully) what they can do with this names. Also, there is no way to understand, if jQuery is used on a particular page or not, it always here, even when the page does not need it.

In cartridge code in SFCC, how to find if product price have changed recently. In case product.getLastModified() is not changing on price change. There is no built in way to do this. I suggest using ProductPriceInfo. You can get priceBook information for any product by Product.getPriceModel(), which returns a instance of ProductPriceModel. This class has a method getPriceInfo(), which will return a ProductPriceInfo class instance with attribute priceInfo : String, which you can use to store information about the date of change for a given price point for a product.

Variation Group in SFCC Technically a variant could be in multiple groups. One way to do this is to get the ProductVariationModel of that variant's master. Then you could set the selected value (setSelectedAttributeValue(String, String)) of the attribute your group is represented by. Finally you can get the collection of groups (getVariationGroups()) that share that selected value. Demandware Docs
