Full Disclosure, I am an NOT online vendor. Let's just get
that out of the way.
Trust issues come from not knowing where & who A vendor really is when shopping on screen. Buying from an unknown website is like throwing money into a black box (or a dark, stinky hole) and then hoping that from out of the darkness a package will arrive in the mail with a coral in it. New sites have to convince me that they are real and that they want to provide a live product at a fair price. Same deal for any LFS
except if I can walk in and see the goods and service folks I can gauge the depth of the hole and smell the air in the store before I open my wallet.
I know you are a vendor on here (full disclosure

) and to encourage sales and trust that helps me trust you alot, as I presume R2R has vetted vendors?
On a website, I like to see a street address (even if it is your moms house or garage

) a phone number where people can at least leave a message (that you will respond to) and likewise a live chat and email for questions (that again you reply from 'quickly' or routinely) are things a vendor might do to develop a customer service presence that builds trust that you really want to do more than take my money, once.
The poll isn't going to get you this kind of answer, imo. Ask people better question will help improve the answers you will get. I am one (older) person and the market is filled with other people who may have more important answers that can help you succeed in this effort. HTH.
Oh, and reefers love free bees, lots of cheap low balling hustlers Jonesing for the next hobby fix. You have to forgive us our many poor habits.
