I'm in process of redesigning a website for my company, in cooperation with a digital agency. Our business is one of the leading companies in our country that sells consumer electronics (notebooks, PCs, smartphones, tablets, cameras etc.).
I have idea to place product cart in fixed position box which displays on any page, any time when user click on the cart icon. For me it is more useful and clear - you can fast check out your cart, edit it etc. Ofcourse after click go to the checkout there will be redirection to new page with checkout process.
Is that any hard data after or against sliding in or pop-up card instead of redirection?
