Question about Garmin Forerunner 945

Hello, I ordered the watch on July 1, 2019 at a price of 689.00 Due to "delays in deliveries from the supplier", it has not arrived yet. I see that the base price of the watch has gone up to 658.00 and that several times it has gone down even with a 16% discount to 552.00 (It was also 552.00 a few days before the delivery that should have been made at the end of August but which never arrived) Should I cancel the order of this product at 689.00 and recommend it today at 552.00? Will it be back at 658 tomorrow? I can understand the delays of the suppliers, but not the prices which change so often...
