Difference of Genmaicha pricing

Here's what i found out. I bought my Genmaicha for Rm35 from Coffee Bean Jaya Jusco. But when i went online to check on what else they have in store for me, i found that it's listed at Rm30 on the website. Why like that ah? Anyone aware of that. I'll give them a call to see why the difference in pricing tomorrow. Makes a difference when i buy a lot, you know, lol. Do you all feel the tulan-ness in me now....
