| ===Orders placed===
| |
| *We placed an order with Ocimum Biosolutions for 1000 mg of ssDNA. The contract they proposed was to deliver 100-200 mg within 14 days, 300 mg within 21 days, and the remaining 500-600 mg within 28 days. After 21 days, Ocimum was able to deliver 10 mg of highly-contaminated ssDNA.

| ===Outcome===
| | *Table template can be seen here: [[Template:Table]] |
| In the subsequent two weeks of extremely tedious negotiations, Ocimum refused to offer any discount or compensation, and failed to guarantee any future delivery schedule, and we ultimately canceled our order.
