A good backyard projector should last you several summers, so you want to buy right the first time. Cheap mini projectors look tempting, but low brightness and quiet speakers will leave you replacing them by next year. Aiming for a solid mid-tier model around $700 gets you true 1080p resolution and enough light output for dusk screenings.
Timing matters here. Tech brands usually launch new models in late spring, which means previous-generation units hit clearance right as outdoor season starts in early summer. Snagging last year's top model gives you premium features without the launch-day price tag.
Remember that a 0% intro APR is a repayment deadline, not free money. If you still have a balance when the 15 months end, regular interest kicks in on whatever is left, so set up automatic payments of $46.67 to clear it on schedule.
