If I have to say that:
"potatoes are so commonly available in that place that every random shop you visit has a store of them as if its their staple food."
Or if I have to say:
"it is so cold over there that rum is so easily available or commonly seen or prevalent everywhere inorder to withstand the cold."
Is there any single word or phrase or a better way to convey that something is very commonly available or seen almost everywhere or easily prevailing ?
