Here are a few tips:

1. Try to buy equipment rather than lease it. This way you can take certain business deductions immediately and avoid long term payments that eat into your cash flow

2. Maximize the number of bills you pay with the credit card you get your 30 day window and the insurance if you are not satisfied with the product

3. Use travel aggregator websites like Cheap Flights, Airline Tickets, Cheap Airfare & Discount Travel Deals - Kayak.com to get the best travel deals
