Do you have Costco? Do you shop on Amazon?
For pillows I have Nest pillows (online mattress retailer). I had to take a bunch of filling out of each but they’ve gotten a lot of compliments. I also have two older pillows, one is down and one is some kind of similar but synthetic fill. Finally I have two fairly flat foam pillows that are in the shams. I put pillowcases on them in case someone takes them out of the sham to sleep with them.
For things that Costco has, towels, mattress pads, sheets in queen and king size you can’t beat the price and quality. For things they don’t have I usually go with well reviewed items on Amazon. I also look for items at discounters like Marshalls, TJMaxx. BB&B is my last option because they are more expensive but if you find a markdown, sale or have a coupon they do have everything.
