Two ways to get a $20 cash trade-in bonus on your old iPads (including iPad 2)

The prices that buyback services are willing to pay consumers for old iPads will begin their slow and inevitable decline following the unveiling of new models by Apple Thursday afternoon. To encourage iPad owners to lock in a top-tier, 30-day price quote before rates drop, both NextWorth and Gazelle are offering AppleInsider readers an additional $20 cash bonus payout on their iPad trade-ins, the details of which follow.

NextWorth

Like other leading buyback services listed in the Trade-In BuyBack Guide, NextWorth aims to make the trade-in process quick and easy for consumers who don't have the time and patience to deal with selling their iPads through eBay, Craigslist, or other venues. To lock in a cash payout that's good for 30 days, readers can use this link to head over to NextWorth.com where you'll be asked to identify your current iPad model and answer a few quick questions about the devices condition and attributes.

NextWorth then spits out a dollar value it's willing to pay for that particular iPad (current max prices below) and asks for a shipping address where it can send a pre-paid shipping box. Once you accept the offer and move on to the "Get Paid" step, there will be a field for a promotional code. Enter promotion code IPAD20 to get an extra $20 cash on any working iPad dating back to, and including, the iPad 2. The offer does not include the original iPad.

You'll then have 30 days to place the iPhone in the box and drop it in the mail. You can also choose how you wish to be paid: cash (via a check that comes within 3-10 days), PayPal (paid immediately upon inspection of your iPhone), or in the form NextWorth Discover Prepaid Card or Target Gift Card (both arrive in 3-14 days).

Gazelle

Meanwhile, Gazelle is offering the same $20 bonus on all working iPads with a trade-in value of at least $75 to new customers only who use this link or one of the links in the table below. The $20 bonus will automatically appear as part of your trade-in offer total near the end of the price lock process when using these links. No coupon or promo code is needed.

Like with NextWorth you can take advantage of the offer by first assessing the physical and operational condition of your iPad by rating it in one of three tiers —  broken, good, or flawless. The ratings include factors like whether the device's screen is cracked or if it has ever been damaged by liquids. A few days after locking in your price quote, a pre-paid shipping box will show up on your doorstep. Gazelle gives a generous 30 day grace period from the time you lock in your trade in offer to the time you need to pack the device — and only the device — securely in the box and drop it in the mail. Alternatively, you can use your own shipping box and simply print and affix a pre-paid shipping label from Gazelle's website.

Gazelle handles all trade-in inspections itself, doesn't nitpick over the trade-in value of devices that arrive in good working order, and will even completely wipe your device of data before passing it along to its new owner. Once the company receives your old iPad, the company will issue a check within 10 business days as long as the device's condition generally matches your online assessment. Alternatively, you can choose to be paid more quickly via PayPal, receive an 5 percent bonus by accepting payment in the form of an Amazon Gift Card, or donate the proceeds entirely to charity.
