okay, i know that many ppl upgrade their ering and even their wband. and i know that some ppl trade in their ering for a bigger one or just keep the original one and buy a whole new one. but um, can you trade in your wband for a bigger one? i didn't read anything here so far about anyone doing that. i have a 5 diamond band (.20's i think, not 100% sure), but i was thinking about getting an eternity band (same size diamonds are fine). but if i do, i don't really need the 5 diamond band anymore so i was wondering if i can trade that in?
