You need a scanner that chews through stacks without jamming, and buying the right one means you only buy once instead of replacing a cheap model next year. Look for something built for office volume that handles duplex scanning automatically.
Timing matters here because back-to-school season in late summer brings office gear sales. If you wait just a bit longer for the new model drop, last year's proven workhorse usually gets discounted.
Remember that the 0% intro APR for 15 months on purchases and balance transfers is a hard deadline, not free money. If you still have a balance left when those 15 months are up, interest kicks in on the original amount from day one.
