Do! The Swap Center is my saviour because we cant return items even if they've only been tested once in Ireland so basically anything i dont like goes straight on to my swap list!
i tried philosophy's hope ina jar, and it sucked for me. i bought it online. it says something about "unused" items when returning, but on the order fowm, it doesn't say anything and you put a # reason why. i just said i had an allergic reaction to it. lol. i only used it a few times, but there was a big air pocket, so it looked like more was used
