There are months where Epson may change the products on the rebate or make it for a few months vs a single month. It's hard to say what they decide per month, but it's usually something they have for most of the year. There may be another one that they do just Signature Worthy or Legacy and others where it's together (like last month and this month).
Our company emails anyone subscribed to our newsletters regarding product updates, promos (rebates) and what not; and you can always adjust (be removed or resubscribe) the subscription per your request.
And holiday's are sometimes extra deals!
