Here in Kansas an EIN and a Retailer's Sales Tax Certificate are two different things. The EIN (Employer's Identification Number) is for businesses who have employees and will be submitting wage taxes. The Retailer's Sales Tax Certificate, I believe, is what you are looking for, and will allow you to purchase beads etc. without paying sales tax (but you will, of course, need to collect and report sales tax on anything sold). It was easy to apply for (and free for us in KS), and makes you appear more like a reputable buyer at markets etc. Alice
