<br/>
Apple has discontinued the 27" Thunderbolt Display. &nbsp;As a result, they are no longer selling LCD or LED monitors under the Apple brand.<br/>
<br/>
To compensate this, we are offering two standard alternative options for customers (usually faculty) who were previously interested in the Apple one.<br/>
<br/>
Option 1:</span></span></p>
<p class="a-size-large a-spacing-none" style="box-sizing: border-box; padding: 0px; margin-top: 0px; margin-right: 0px; margin-left: 0px; font-family: Arial, sans-serif; text-rendering: optimizeLegibility; font-weight: 400; color: rgb(17, 17, 17); margin-bottom: 0px !important; font-size: 21px !important; line-height: 1.3 !important;">
<span style="font-size:12px;"><span style="font-family:arial,helvetica,sans-serif;"><span class="a-size-large" id="productTitle" style="box-sizing: border-box; text-rendering: optimizeLegibility; line-height: 1.3 !important;"><strong>HP Pavilion 27xw 27-in IPS LED Backlit Monitor</strong></span></span></span></p>
<p class="a-size-large a-spacing-none" style="box-sizing: border-box; padding: 0px; margin-top: 0px; margin-right: 0px; margin-left: 0px; font-family: Arial, sans-serif; text-rendering: optimizeLegibility; font-weight: 400; color: rgb(17, 17, 17); margin-bottom: 0px !important; font-size: 21px !important; line-height: 1.3 !important;">
<span style="font-size:12px;"><span style="font-family:arial,helvetica,sans-serif;"><span class="a-size-large" style="box-sizing: border-box; text-rendering: optimizeLegibility; line-height: 1.3 !important;">Resolution is 1920 x 1080<br/>
Warranty: 1 Year<br/>
Price for customers is: <strong>$299.99</strong><br/>
<br/>
Option 2:</span></span></span><br/>
&nbsp;</p>
<p class="a-size-large a-spacing-none" style="box-sizing: border-box; padding: 0px; margin-top: 0px; margin-right: 0px; margin-left: 0px; font-family: Arial, sans-serif; text-rendering: optimizeLegibility; font-weight: 400; color: rgb(17, 17, 17); margin-bottom: 0px !important; font-size: 21px !important; line-height: 1.3 !important;">
<span style="font-size:12px;"><span style="font-family:arial,helvetica,sans-serif;"><span class="a-size-large" id="productTitle" style="box-sizing: border-box; text-rendering: optimizeLegibility; line-height: 1.3 !important;"><strong>Dell Ultra HD 4k Monitor P2715Q 27-Inch Screen LED-Lit Monitor</strong><br/>
Resolution is: 3840 x 2860 (4k)<br/>
Warranty: 3 Years<br/>
Price for customers is: <strong>$545.99</strong><br/>
<br/>
If a customer is interested in something different, we can absolutely accommodate their needs. &nbsp;Simply search through our distributors for whatever they would like. &nbsp;These two are meant to act as standard "go-to's" which you can offer. &nbsp;Both will be in the products table under Monitors.<br/>
<br/>
Although they do have a large price difference between them, the 4k option is still around half the price of the old Apple Thunderbolt Display. &nbsp;<br/>
<br/>
It is important to note that all Macs aside from the Retina Pros will need an adapter to connect: either Mini DisplayPort to HDMI or USB-C to HDMI.<br/>
<br/>
Any questions about these two options can be brought up to Kira or Jackie.<br/>
<br/>
Thank you for all that you do,<br/>
<br/>
-Jack</span></span></span></p></body>

<body>Hi everyone,<br/>
<br/>
Please read this email it is VERY IMPORTANT!<br/>
<br/>
If you don't already know, there is an Ordered Folder that is kept by Kira's desk. If you can't find it, let me know. Whenever we get an order in, and we don't have the laptop in stock, the order (along with all of the agreements, if applicable) should be paper clipped and placed in this folder. Once the laptop has arrived, whoever is checking it in, it is your responsibility to:<br/>
<br/>
1. Check the PO reference (in this box it will list whether the laptop is for a specific CO, RR, or stock)<br/>
2. Check the Ordered Folder for the corresponding CO or RR papers<br/>
3. Place the laptop with the Order papers and BEGIN BUILD!<br/>
<br/>
We have had a few orders that have been delayed due to people not following this process. I understand that not everyone was aware that this folder existed, but now everyone will be held accountable.&nbsp;<br/>
<br/>
<em><strong>*We currently have ~15 orders waiting for laptops to come in that are in this folder*</strong></em><br/>
<br/>
<br/>
Thank you,<br/>
Alex Swan</body>
