less. these are two things i get regularly eg: 3m filtrete airconditioning filter replacements https://www.amazon.com/gp/product/B000BO96IW/ref=oh_aui_detailpage_o00_s00?ie=UTF8&psc=1 .. literally $20 on amazon prime singapore now and $25 in stores.

there's literally no reason for me to get amazon prime anyway now. one time purchases do not justify amazon prime. also i hate the app. use a proper website so that i can search a page of 20 items at one glance please. that's why i do all my sundry shopping with redmart
