ME2011 Robot Store

Store Operation and Rules

1. Store is managed by the ME2011 staff. Store is open just after Monday lectures staring in early November. Store location is in the lecture room. Also open during staff office hours as we get closer to the Robot Show.
2. Cash only, exact change. No checks, no credit cards, no IOUs, no change. And did we say no change?
3. Limited quantities of each item are carried because we can't handle a large inventory. We (may) reorder when we run out, but don't expect everything to be in stock at all times.
4. For each purchase, you may only buy quantities up to what's listed under the Limit column.
5. Consult your electronics text, the Jameco web site (www.jameco.com), the All Electronics site (www.allelectronics.com) or the Stamp interfacing section of the Robot Project web site for details on items and suggestions on component use.
6. You can also buy components at Radio Shack, AEI Electronic Parts and Ax-Man. See the Where-To-Buy section of the project web site.
7. Exact amount, cash only. No checks. No change. Thanks!.
