Where can I find the best deals on bathroom fixtures like squat pans?

I visited a bathroom fixture shop to find durable toilet tanks under $100 two days ago. I wanted something strong but also budget friendly for my home upgrade. I also wanted something that does not leak or crack after short use. But when I checked different options I felt confused. Some tanks were under budget but seller said quality is very basic. Some looked strong but price was slightly above my limit. Some brands looked similar but durability claims were different. One seller keep saying every tank under $100 is same quality but I was not believing him. I could not trust them. I could not decide confidently.
Then I visited another shop in the same area. Some local brand tanks were within budget but finishing looked average. Some imported options were slightly higher in price but felt more solid. Some compact tanks looked good for small bathrooms but installation cost was not clear. I remembered my cousin bought a cheap toilet tank before and it started leaking after few months so he had to replace it again. That made me more careful again. One worker was explaining price difference but I was getting more confuse because durability and price were not clearly linked. That made me hesitate even more.
To check more options I searched online while scrolling many marketplaces including alibaba. I found many toilet tanks under $100 mostly in basic ceramic and plastic body designs. Some sellers say you can get durable options in this range if you choose simple models without extra features. Some reviews say mid range local brands perform better than cheap imported ones. Some listings also show bulk deals that reduce price further. This made me excited but also confused again. Now I am thinking should I choose simple local tank under budget or increase budget slightly for better durability what would you do in my place?
