I don't believe there was a limit. Yeah, the prioritization doesn't happen that way, unfortunately. As I mentioned with my order, it all depends on how the orders are processed, and what system is used for fulfillment. I am very familiar with the 'behind the scenes' process that governs this supply chain from a distributor side (I don't work for Target but do work on the distributor side for all major international retailers). Sometimes there is no rhyme or reason, it depends on a variety of factors, such as their own system, how the rep processes it, how fast the order moves through the entire chain, from order generation to 'fulfillment' stage, etc etc.
As a consumer, I've ordered from Target many times before, and each time I was not charged the lower price. And phone and e-mail support was always severely delayed or non-existent or 'cookie cutter response-like' unfortunately. The CS reps can't always see 'all levels' deep as to what 'exactly' is going on, because of different system views that not everyone has access to. So this fact definitely creates increased aggravation on the consumer side, as folks are trying to get info....
I'd say if you have not received cancellation notices, your order should still be in the system, but if you're concerned don't rely on e-mail. Talk to CS, and if you get no where insist on a supervisor if it goes on to long.
