Best way to get a grx di2 groupset? parts or combined?

Where are you all finding GRX groupsets? The shifters seem to be pretty hard to find, especially the right. And is it more cost effective to buy as a group or is it all the same?

Ordered the whole group July 2021, 
It’s due to arrive next week. Only took 8-9 months!!

I've been looking to get a Di2 set but went with the mechanical GRX because it's available.  Still want the Di2 but it will have to wait.

I don't think anybody knows. I have been trying to finish out a road di2 build since last fall and used parts keep jumping in price on eBay. It's approaching original MSRP for some parts. God help you if you need hydro levers. Shimano is so far behind in production. This might become a SRAM 12 speed build since the parts I already own haven't lost any value. 

@dangle which parts are you having a hard time finding, is it just the levers?

I’m still waiting on right/rear shifter and caliper as well as di2 battery. I thought everything was in my last shipment but no such luck. So a little more waiting 

I was fortunate enough to order the group set mid January, and got everything mid March, through my LBS.  Well worth the upgrade from mechanical imo.  I believe they had some more components in stock too. Northwest Tri and Bike in Kent, WA.

I'm not looking for levers, but most of the other di2 pieces for a road rim brake bike. Levers, battery and an external junction b are all I have to upgraded my mechanical rim brake build to di2. I even have a set of used 785 series levers and brakes (di2 and hydro brakes) to sell for another build that went AXS instead. I have been tracking prices and making bids on the di2 stiff for a months and it seems like used Shimano stuff keeps going up in value. Even 6800 series di2 bits seem to have gained value on the secondary market.
