I had not long ago came across Rohto Eye Drops (just a month back only). Immediately, I was attracted to one of the range: ROHTO COOL (Redness Relief) which was also used by Michelle Phan.
You can see her vid in the Rohto site too: http://www.myrohto.com
I've seen raves and reviews and saying how good it was, I was so willing to try it! I'd looked over the internet to find a local source or spree but most of them are only taking in the Japan version of Rohto eye drops, currently popular one is the Lychee (so the eyedrop will taste like lychee? ^_^")
But I'm only interested in US version, so I intend to go to buy it from Ebay.
I bought from this Ebay seller: http://myworld.ebay.com.sg/sokopovo/
He was selling the Rohto eye drop in a pack of 3s, which I think is more worth to get it. (Actual LINK)
Price is US$16.90 for 3packs, shipping to Singapore was $6.99 (however no tracking), total convert to SGD was $34.14.
After calculation, each pack is about SGD$11.38. Not bad eh~
