Context: This is a simple story of an online purchase that went well despite a problem . The fact that this is sufficiently rare to make me want to write about it is sad , but that 's how it is . What happened was , I need a new computer monitor , knew the one I wanted , and the manufacturer 's web site suggested CDW as a reseller . Turns out CDW has a decent web - site that let me track it down despite some fuzziness about the model designation , the price was reasonable , and in fact had two of them sitting in a warehouse in a nearby suburb .

Answer:

They were purchasing a display screen
