Your page size is huge 11MB https://gyazo.com/e813e9f318534f1a0a30d3ac868fe581 And all of this are images. So, change png images to jpg (for example image /wp-content/uploads/2020/12/Loud-Bluetooth-Speakers-20w-M-500×750.png in png format is 2.4MB and 3s to load it https://prnt.sc/1383nx3) and optimize your images after that (use Tinypng service for example https://tinypng.com/ ) and reduce the page size to 2-3Mb.
